Recovering files from Windows shadow copies. How to recover deleted files in Windows Windows 7 file recovery program

One of the reasons why the system does not work correctly or is completely unable to start is damage to system files. Let's find out the various ways to restore them on Windows 7.

There are many reasons why system files become corrupted:

System malfunctions;
Viral infection;
Incorrect installation of updates;
Side effects of third-party programs;
Abrupt PC shutdown due to power failure;
Actions of the user himself.

But in order not to be the cause of the problem, its consequences must be dealt with. The computer cannot fully function with damaged system files, so it is necessary to eliminate this malfunction as soon as possible. True, this damage does not mean that the computer will not start at all. Quite often this does not manifest itself at all and the user does not even suspect for a certain time that there is something wrong with the system. Next, we will study in detail various methods for restoring system elements.

Method 1: Scanning with the SFC utility via the “Command Line”

Windows 7 includes a utility called SFC, the direct purpose of which is to check the system for damaged files and then restore them. It starts through "Command line".

Click "Start" and go to the list "All programs".

Go to the catalog " Standard".

Find the item in the folder that opens "Command line". Right-click on it ( RMB) and select the option to run with administrator rights in the context menu that appears.

Will start "Command line" with administrative powers. Enter the expression there:
Attribute "scannow" it is necessary to enter, since it allows you to not only check, but also restore files if damage is detected, which is what we actually need. To run the utility SFC click Enter.

The system will be scanned for file corruption. The task completion percentage will be displayed in the current window. If faults are detected, objects will be automatically restored.

If damaged or missing files are not found, then after scanning is completed, "Command line" a corresponding message will be displayed.

If a message appears that problematic files have been found, but they cannot be restored, then in this case, restart the computer and . Then repeat the scanning and recovery procedure using the utility SFC exactly the same as described above.

Method 2: Scanning with the SFC utility in the recovery environment

If your system does not start at all even in "Safe Mode", then in this case you can restore system files in the recovery environment. The principle of this procedure is very similar to the actions in Method 1. The main difference is that in addition to entering the command to launch the utility SFC, you will have to specify the disk partition on which the operating system is installed.

Immediately after turning on the computer, after waiting for the characteristic sound signal notifying you that the BIOS has started, press the button F8.

The startup type selection menu opens. Using arrows "Up" And "Down" On your keyboard, move the highlight to the item "Troubleshooting..." and click Enter.

The OS recovery environment will launch. From the list of action options that open, go to "Command line".

Will open "Command line", but unlike the previous method, we will have to enter a slightly different expression into its interface:
sfc /scannow /offbootdir=c:\ /offwindir=c:\windows

If your system is not located in a partition C or has another path, then instead of the letter "C" you need to specify the current local disk location, and instead of the address "c:\windows"- the appropriate path. By the way, the same command can be used if you want to restore system files from another PC by connecting the hard drive of the problematic computer to it. After entering the command, press Enter.

The scanning and recovery procedure will begin.

Attention! If your system is so damaged that the recovery environment does not even turn on, then enter it by starting the computer using the installation disk.

Method 3: Restore Point

You can also restore system files by rolling back the system to a previously created rollback point. The main condition for performing this procedure is the presence of such a point, which was created when all the elements of the system were still intact.

Click "Start" and then through the inscription "All programs" go to the catalog "Standard", as described in Method 1. Open the folder "Service".

Click on the title "System Restore".

A tool opens for resuscitating the system to a previously created point. In the start window you don't need to do anything, just click the element "Further".

But the actions in the next window will be the most important and crucial step in this procedure. Here you need to select from the list the restore point (if there are several of them) that was created before you noticed problems on your PC. In order to have the maximum variety of choices, check the box "Show others...". Then select the name of the point that is suitable for the operation. After that click "Further".

In the last window, all you have to do is check the data, if necessary, and click the button "Ready".

Then a dialog box will open in which you need to confirm your actions by clicking the button "Yes". But before this, we advise you to close all active applications so that the data they work with is not lost due to a system reboot. You should also remember that if you perform the procedure in "Safe Mode", then in this case, even after the process is completed, it will not be possible to cancel the changes if necessary.

After this, the computer will restart and the procedure will begin. After its completion, all system data, including OS files, will be restored to the selected point.

If you are unable to start your computer in the usual way or through "Safe mode", then the rollback procedure can be performed in the recovery environment, the transition to which was described in detail when considering Method 2. In the window that opens, you need to select the option "System Restore", and all other actions must be performed in the same way as with a standard rollback, which you reviewed above.

Method 4: Manual recovery

First you need to determine which object has damage. To do this, scan the system with the utility SFC, as described in Method 1. After a message appears indicating that the system cannot be restored, close the "Command line".

Using a button "Start" go to the folder "Standard". Look for the name of the program there "Notebook". Click on it RMB and choose to run with administrator privileges. This is very important, because otherwise you will not be able to open the required file in this text editor.

In the interface that opens "Notepad" click "File" and then choose "Open".

In the object opening window, navigate to the following path:
C:\Windows\Logs\CBS

In the file type selection list, be sure to select the option "All files" instead of "Text Document", otherwise you simply won’t see the element you need. Then check the displayed object called "CBS.log" and press "Open".

Text information from the corresponding file will be opened. It contains data about errors detected as a result of checking by the utility SFC. Find the entry that corresponds in time to the completion of the scan. The name of the missing or problematic object will be displayed there.

Now you need to take the Windows 7 distribution kit. It is best to use the installation disk from which this system was installed. Unpack its contents onto a hard drive and find the file that you want to restore. After that, start the problem computer with LiveCD or LiveUSB and copy and replace the object extracted from the Windows distribution into the desired directory.

As you can see, you can restore system files either by using the SFC utility specially designed for this, or by applying the global procedure of rolling back the entire OS to a previously created point. The algorithm of actions for performing these operations also depends on whether you can start Windows or whether you have to troubleshoot problems using the recovery environment. In addition, it is possible to manually replace damaged objects from the distribution.

Any of us can accidentally delete a file from our computer, or press the format button on our hard drive unknowingly. Both situations lead to the fact that the necessary data will be deleted from the Windows 7 computer. It is a mistake to think that it is impossible to recover deleted files on Windows 7. There is a special program for this, Any Data Recovery.

Recover lost and deleted files in Windows 7

The user may find himself in various situations when he needs recover deleted files from computer. For example, while surfing the Internet, you can accidentally catch a virus that can partially damage some documents, photos or music on your computer. The stupidest situation is to delete a file yourself and then empty the trash. This happens, and very often - I’ve encountered it myself more than once. Perhaps the most unpleasant incident can be called a hardware failure of the hard drive, which fails at the most inopportune moment. In such situations, users usually panic because they believe that deleted files on Windows 7 can no longer be recovered and are lost forever. The same can be said about formatting your hard drive.

You need to understand that deleting files does not mean that you have lost access to the data completely and irrevocably. The deleted file is only excluded from the directory, but the information on it is not reset.

How to recover deleted photos on your computer

Most often, people are looking for a way to recover deleted photos on their computer. If some files can still be recreated somehow, then with photographs it is completely different. For users, this is a great memory of various events, memories, etc. With help you can recover not only deleted photos, but also files of other types.

How to recover files on Windows 7 for free

Any Data Recovery program offers a free way to recover data on Windows 7. The list of supported files includes: images and photos, audio files, videos, word/excel/pdf documents, emails, etc. The utility interface is very simple and intuitive, so you can recover lost data even the most advanced PC user can handle the data.

Instructions

1. Download Any Data Recovery from the official website and install it on your computer (Please note that Any Data Recovery is available not only on Windows, but also on Mac).

2. Launch Any Data Recovery. In the window that opens, select what type of files we want to recover. Click on the “Next” button.

4. The program will begin scanning the drive you selected. It will take some time.

5. When the scan is completed, you will see a list of files. To select the ones you want to restore, use the preview function. The “Deep scan” function involves a deeper scan.

6. Mark the required files and click on the “Recover” button. The files will be restored to the location you specified.

It is possible to recover deleted files for free Windows 7, not only that, even the software supports other models, for example, Windows 10/Windows 8.1/8/7/Vista/XP etc. In addition, Any Data Recovery is a useful tool with a user-friendly interface that is significantly superior in quality to its analogues. You don't need any special knowledge. All you need to do is download this free program, install it (it won't take much time) and start using it. You should make sure that everything is configured correctly so that you never accidentally lose important data. Overall, this is a useful program with many interesting features.

Often, novice users delete necessary data from a laptop or accidentally lose it without knowing whether it is possible to recover deleted files, including those on the desktop, and how to do it. There may be quite simple situations where lost documents are literally a couple of clicks away, but there may also be more serious problems that require the use of special applications to solve.

Recovering from the Recycle Bin

All files after deletion while maintaining the standard computer settings fall into the so-called. Recycle Bin is a special folder on the desktop, by opening which you can easily restore any deleted information by highlighting the desired object and selecting the appropriate item in the menu. But files can be deleted permanently without being placed in the trash.

Inexperienced users often accidentally delete application shortcuts and documents from the desktop, believing that if they are gone, then the rest of the program has also been deleted entirely. In this case, many people do not know how to recover deleted files. This is very easy to do, even if the basket is empty. There are two options:

Roll back the system to the nearest restore point;
Find the program in the main menu of the Start button and drag the desired shortcuts to the desktop.

The second option is preferable, but if lost programs and documents have disappeared from the list of the main menu on the computer and you do not remember the directory in which they were installed, you will have to use the first.

If you are deciding how to recover a deleted folder from your desktop, and the erroneous action was performed recently, then you probably won’t even have to go to the Recycle Bin. Deletion can be canceled by simultaneously pressing hot Ctrl and Z.

Using a restore point

It is important to understand that rolling back to a previous restore point will not return the program, documents and files if they were deleted. In this way, only erased shortcuts on the desktop can be returned to their place. Here's how it's done using Windows 8 as an example:

A window will open in which, by default, you will be asked to restore to the most recent checkpoint. If necessary, you can specify any other existing restore point.

We use third-party applications

If data and documents from the laptop’s hard drive are completely deleted and cannot be returned using standard OS tools, you will have to use special utilities to recover deleted files. It is important to remember the main rule that increases the chances of successful data recovery - do not write anything to the disk partition that you will be working with later.

Recuva is a simple free utility

The most famous and simple application with which you can recover deleted files is the free Recuva. During installation, select the partition of the disk that does not contain any data to be recovered. The operating principle of Recuva and other similar utilities is approximately the same:

After the scan is completed, the recovery wizard will display on your desktop a list of all the lost documents that it was able to detect. The utility will be able to restore those marked with a green circle without any loss. If the icon color is red, then this file most likely cannot be returned - a recording has already been made over it and most of the data and information about the file are completely lost.

All that remains is to select the files (you can use the corresponding function to search for specific photos and documents), select the directory to save and click “Recover”.

PhotoRec is another functional free utility

The name of the program should not be misleading. The utility recovers not only photos, but also most other types of files. Its advantage is that there is no need for installation - free PhotoRec is downloaded from the office. site in the form of an archive, unpacked, after which you can work with it. This is an important property for such applications - the program can be immediately downloaded to a flash drive and worked with it.

The scheme for returning long-lost information is as follows:

After launching PhotoRec, the main window immediately opens, in which the drive is selected in the top drop-down menu - you will have to work with it during data recovery. The program also works with img format images created in other applications.
Below in the window there is a list in which you can select a full disk scan or individual sections.
Below, you can set the file type to scan by clicking File Format. If you skip this step, the program will try to recover all accidentally deleted data that it can detect.
You can specify a folder to save the recovered information by clicking the Browse button. In addition, in the File System type menu you will need to select a file system. If you work in a Windows environment, check the second box. Ext 2-4 system is the standard for Linux.

Let's compare the considered applications

For novice users, the PhotoRec program is no less suitable than the above-described Recuva. It is more powerful - it often extracts data from the computer better, but there is still one unpleasant feature. Free PhotoRec does not allow you to view the found files after scanning and select something specific from them. This must be taken into account when working with large hard drives - if you do not specify in advance which files are to be restored, everything will be saved.

Above we discussed the simplest free applications for retrieving accidentally deleted information on the desktop or lost documents after formatting flash drives, hard drives and other media.

It is important that PhotoRec, unlike Recuva, is also a cross-platform utility, i.e., it can work in any operating environment.

Recuva operates only under Windows, starting from the seventh version of the OS. There is also more advanced semi-professional and professional software for retrieving deleted data from any drive. Almost all of them are paid, but the loss of information often costs more. If necessary, you can use the applications R-studio, File Scavenger, Power Data Recovery, Data Rescue PC, etc.

How to recover deleted files on your computer

People often come to me asking to recover photos, music, and other files accidentally deleted from their computer. However, this does not always happen by accident, for example, a girl quarreled with a guy, and out of bitterness deleted all the photos with him, and later, having made peace, she clutches her head, “What have I done!” But this is an example; situations in life are different.

Many people think that these files cannot be returned, or you need to contact a specialist who will restore your documents for money. Meanwhile, the file recovery process itself is not that complicated, and following the instructions given in this article, even a novice PC user can handle it.

Recovering deleted files in windows 7, 8.1, 10

First of all, you should look in the trash, if the necessary files are in it, then restoring them is as easy as shelling pears. Just select the desired file and click “Restore selected objects” or “Restore all objects”.

All deleted files always end up in the Recycle Bin and are stored there for some time, unless, of course, you specifically empty the Recycle Bin. If there are no files in the trash, read on.

If the deleted files are no longer in the Recycle Bin, it is still possible to recover them. For this we need a special program Recuva, you can download it from the official website of the developers. There are paid and free versions; the free version is quite sufficient for us.

After downloading, install the program.

At the last step, click “Run Recuva” to start the program.

Now let's move on to file recovery. In the window that opens, select the type of file to be restored, picture, music, video, document, etc., this will significantly speed up the search for the deleted document.

Now select the folder where the file was located before it was deleted; if you don’t remember, leave “Not exactly known.”

Now click “Start” and you can go about your business, the search process is quite long. The speed of the process depends on the size of the hard drive and the specified search parameters.

After finishing the search, just select the files you need and click restore.

This completes the file recovery process, as you can see everything turned out to be very simple.

How to recover permanently deleted files in Windows?

Sometimes, for some reason, people accidentally completely delete important documents from their computers. If you have ever encountered this, then today’s article, where I will tell you how to recover permanently deleted files in Windows, will help you. You might be surprised, but even files deleted from the Recycle Bin are not completely removed from your computer and are stored on your hard drive for some time. Therefore, if a little time has passed since the document was deleted, then there is still hope that they can be restored. This cannot be done with improvised means, so I advise you to download the Handy Recovery program at this address: handy recovery and install it on your computer.

This program is also good because in addition to restoring deleted files, it can also restore files infected as a result of virus attacks. If you want to know more about this, sign up in the comments form.

To do this, launch the Handy Recovery program, after which it will ask you to select a local disk for analysis. Select the disk on which the deleted document was located and click “Analyze”, after which the program will begin to analyze this disk for the presence of recoverable files.

When the analysis is complete, you will be able to see all the files that can be returned. Select any of them and pay attention to the “recovery probability” tab, where you can see the probability of what the chances are of getting your files back without damaging them. To continue, click the “restore” button.

Next, a window will appear in which, by clicking the “browse” button, you can select the folder where the file will be restored. Now click “OK” and the process will begin. The time it takes to restore a file depends on its size.

After the process is completed, you will find your previously deleted document in the same place from which you deleted it. I would like to add that this program does not guarantee you complete document recovery, and in principle, there are no programs that can guarantee this. But another useful feature is that it can restore deleted Chrome history. That’s all for me! If you have any questions or have something to add to this topic, write in the comments. And with this I say goodbye to you, bye everyone.

Recovering a deleted file or folder

I think many people have had a situation in which you accidentally or someone intentionally deleted a file or folder with very important information. And naturally the question arose: How to recover a deleted file or folder? The first thing you need to do is not to be upset or upset, because almost any information deleted from a computer/laptop, USB drive can be easily recovered by yourself, but for successful recovery you need to understand one rule:

There is no need to write files or install programs on the hard drive or USB flash drive that contains the information you want to recover. This is connected with the principle of deleting information, the fact is that when you click on the “delete” button, the information is not actually deleted, but only its header is erased, the file or folder itself remains, but the next time it is written to a disk or USB, it is replaced in the place where a deleted file or folder is located, new information is written, the old one can no longer be restored.

Ways to recover a deleted file or folder.

1) Check cart

The first and simplest thing to do is check the Recycle Bin to see if there is a deleted file or folder there. To do this, click on the Recycle Bin shortcut on the desktop and if you see a file or folder there that you accidentally deleted, right-click on it and select “Restore”. The data will be restored to the same location where it was before it was deleted.

If you are unlucky and you do not find the deleted file or folder in the trash, then you need to use one of the recovery programs described below

2) Use the free data recovery program Recuva.

First of all, go to the Recuva website and download the latest version of the program. Then you start installing the downloaded program, the installation process is very simple, the first step is to select the installation language.

Then we specify additional parameters (whether to create a shortcut on the desktop, whether to search for program updates...), you can leave them as default. Please note that if the deleted file was located on the disk where the operating system is installed (often drive C), then the Recuva program should not be installed on this disk, otherwise by installing it you may overwrite the file and it will not be possible to recover it. To select a different drive for installing the program, click the "Advanced" button and specify a different path for installing the program.

After this, you will be prompted to install the Google Chrome browser; if you do not want to install, uncheck the box.

After installation, the Recuva wizard will launch to help you recover your files or folder. I strongly recommend using the wizard, as it is more understandable and convenient. Click "Next"

Selecting the type of recovered file

Select the location where the file or folder was located.

Check the box "Enable in-depth analysis" and click "Start".

After this, the search for files will begin, this can take up to several tens of minutes, depending on many factors (computer power, disk or USB device capacity, disk speed, USB device, etc.).

After searching, you will see a list of files that can be recovered. If you want to get more detailed information about the files, you can click on the "Go to advanced mode" button.

To restore a file, check the boxes next to them and click the "Restore" button, then indicate where to restore the file and within a few seconds the file will be restored.

3) Using the paid program EasyRecovery.

I, like many, am for free software, but in this article I will describe file recovery using a paid program, since during my test recoveries this program saw more deleted files than Recuva (2385 files versus 2461). I would recommend using this program if the free one did not help. You will still not lose anything, since with this program you can find deleted files for free, but to restore these found files and folders you will need a license key.

So, first of all, download the latest version of the EasyRecovery program (in this example I will use the Home version). Let's install... the process is not complicated, we agree with everything and click "Next", let me remind you that the program must be installed on the volume (disk) from which you will not restore the file or folders, since you can overwrite the file or folder being restored. After installation, run the program, the first window to appear is the licensing window, which you can skip if you click “Run as a DEMO”. The first EasyRecovery window appears in front of us, click “Continue”.

In the next window, select the location where the file that needs to be restored is located.

The next step is to select a recovery script. If the file or folder was simply deleted, it is recommended to select "Deleted File Recovery", if the hard drive/USB flash drive was formatted, you must select "Formatted Media Recovery".

After this, an information window will appear in which all the specified search settings are indicated; if you have not confused anything, click “Continue”.

The search for files will begin, this process may take quite a lot of time, depending on the volume size of the hard drive or USB device, the power of the computer, etc. After the entire disk or USB flash drive is scanned, all deleted files will appear in front of you, divided into groups depending from expansion. If you click on a file and try to open the file (Open) or save it (Save as), you will be prompted to enter a license key; without it, the file will not be restored.

I hope this step-by-step guide helped you recover your files and folders, saving a lot of time and possibly money. In the future, I recommend using backup of important files, if possible, store important files on several media or at least in different folders.

How to recover deleted files and data from a computer Windows 7, 8, 10, recovery programs, recover data after formatting

The first thing you need to do if you need to restore a file is to run a search in all subfolders of all disks, and also simply look in the Recycle Bin. There is a possibility that the data was not deleted, and you simply do not remember its location, or it was deleted using the Del key followed by confirmation, which in essence is also not deletion, but only moving to a system container called “Trash”. Restoring it will be easy, unless of course you have emptied the Recycle Bin before. If the file you are looking for is there, you can easily find it by sorting it by date of deletion. Right-click on its icon and select Restore.

Pay attention to the column in the Recycle Bin Original location - this is the path where the recovered file will end up.

In addition, if you are a user of any cloud synchronization service (for example, Google Drive or DropBox), we recommend that you look in the cloud storage trash.

We use third-party utilities

If the required file was not found as described above, the recycle bin was emptied, or a complete deletion was performed using the “Shift+Del” combination or special software. In this case, you should resort to the help of one of the many third-party utilities. They will help if during the time that has passed since the deletion, no data has been written to the disk that previously stored this file.

Hetman Partition Recovery

With this program you can recover files of any type. A high-quality low-level search algorithm will allow you to recover the maximum amount of data even in the most complex cases when file tables are empty or missing. Restoration occurs based on start and end signatures. You can regenerate data not only from a hard drive, but also from any removable storage device.

Cleaning the WinSxS folder in windows

The procedure is as follows: select the logical drive or removable media from which the document was most likely deleted.

A window will appear with a choice of analysis - quick and complete. The difference is serious. A quick one will take place in just a few moments - it will produce few results, a full analysis will work more efficiently and deeply. The entire surface of the disk will be carefully scanned and you will be given the most complete information. Having selected the type of analysis, click “Next”.

Having completed the process, the utility will return the disk structure by marking the recovered files with a red cross in the place from which they were deleted.

Mark the documents that require recovery and click “Recover”. Before saving, you can view the contents of any file.

EaseUS Data Recovery Wizard

Immediately about the shortcomings of the utility - it is paid, the free version allows you to recover no more than 2 GB. Secondly, you cannot create a bootable recovery disk using it. In the English version, the main menu of the program looks like this.

As you can see, everything is quite simple. Three icons: Recover deleted files, Full, Partial (partitioned) recovery. By selecting Complete Recovery in the next window, check the file types to search.

Click Next - select the drive and Next again.

After waiting for the Searching procedure to complete, the names and sizes of the files will be displayed in Explorer; to restore, select the ones you need and click “Recover.” Specify another drive where you want to save the information.

The results of the work are encouraging - most of the files were recovered.

CardRecovery

This small-sized free utility specializes more in flash drives and SD cards. It works quickly and very efficiently.

Ways to format a flash drive on MacOS

The interface is in English, but simple and intuitive. We specify the removable media, click Recover and wait for the scan results.

Recuva

Probably one of the most famous and recommended programs for these purposes. We will recommend her too. It is completely free. A high-quality simple Russian-language interface is available here.

The place from where we will restore or mark the item It is not known exactly - and again “Next”.

A list of found documents will open, mark the required ones with a checkmark and click the “Recover” button.

You can view the data by first switching to advanced mode.

The main thing is not to restore data to the place where it was lost; use another disk or media for this.

Recuva is available not only for a computer, it can also be successfully used on a smartphone (Android).

Photorescue

This utility is designed to return lost photos from SD cards and flash drives.

By running the utility as administrator, select the physical disk. During scanning, the program will ask for some parameters (intervals, cluster size). You can leave it as default. Once the scan is complete, you will see the results, where you can select files and save to your computer.

Restoring system files in Windows 7 or Windows 8/8.1 is an interesting topic. Especially if the operating system starts to fail, but we don’t have a recovery image and we forgot to turn on system protection so that recovery points can be created. In this case, we will not be able to restore the system from the image, we will not be able to roll back Windows to the created restore point, and we are also too lazy to reinstall the system, since this will take the whole day. And right here we have another chance to return Windows to normal - try to restore system files. In this article I will try to fully cover the topic so that we can revive our computer in any situation.

1. Recovering system files on a busy system

If our computer somehow turns on, then we do the following. (if it does not turn on, see section 2 of this article)

Open the Start menu. In the search field we write “Com”. On the element " Command line"Right-click and select " Run as administrator»

In the command line that opens we write

sfc /scannow

We wait a little

If your system is ok, you will see the following image

If your Windows was broken, you will see the following

System files were successfully restored. We reboot and immediately turn on system protection to create restore points so that next time we can simply roll back the state of the computer to a couple of days ago and that’s it.

It happens that when scanning the system, the sfc.exe utility found damaged files, but could not fix them. In this case, I would restore system files in Safe Mode. If the same thing happens in safe mode, read the last paragraph 4 of this article.

If your computer does not boot at all, as discussed at the very beginning of the article, then read the next paragraph.

If our computer does not want to boot at all, then we use the recovery environment. You can load into it:

Pressed when turning on the computer F8 repeatedly
Booting from a boot (installation) disk or flash drive

The first option will work if we have a boot partition that the system created when partitioning the disk when we installed the system. Boot partition size:

Windows 7 - 100 MB.
Windows 8 - 350 MB.

In any case, try pressing F8 several times during boot. A window should appear with additional download options. Choose Troubleshooting computer problems.

In the next window, select the keyboard input method. Select the language in which you have set the administrator password (if there is no password, you can immediately click Next >).

Select a user with administrative rights and enter a password if you have one. If there is no password, just click OK.

Select the command line.

If you are unable to enter the recovery environment using the F8 key, you will need to boot from the installation (bootable) flash drive or disk. You can boot from disk in the same way. Only in this case you need to put the DVD-RW (optical disc reader) first in the boot priority.

I like to boot from removable media using the boot menu. On ASUS motherboards it is usually also called by the key F8.

After booting from a flash drive or disk, I saw the following picture. I choose Windows Setup- Windows installation.

We wait until all installed Windows are found.

We choose the one that does not turn on for us. And here CAREFULLY! We remember the letter that the recovery environment assigned to your system (in the Folder column). I have this D.

Select Command Line.

Enter the command

sfc /scannow /offbootdir=D:\ /offwindir=D:\windows

Instead of D, you substitute your letter. Press Enter and wait for the scan to complete

The virtual machine from which the screenshot above was taken had a blue screen, so I was not surprised that system files were found and restored.

3. How to find out the drive letter with Windows installed

If you succeed using the key F8 call up the “Advanced boot options” window and select “Troubleshoot computer problems”, then we need to find out the drive letter where Windows is installed that was assigned by the recovery environment. This can be done in two ways

1. Call the notepad with the command

Open menu in notepad File and choose Open…

Left click Computer and in front of you there will be disks with letters.

You can go to the disk and make sure what and where.

2. Use the utility DISKPART

On the command line enter:

diskpart- call the utility for working with disks.

list disk- look through the list of disks.

select disk- I select the hard drive I need.

detail disk- I call up information about this disk.

4. For Windows 8/8.1

If the sfc utility was unable to restore damaged system files, then you need to try to restore the storage of these system files. The place where copies of working system files should be located. As I understand it, it is located at C:\Windows\WinSxS. That is, we must first fix the file storage, and then use the “SFC / Scannow” command to restore Windows system files.

4.1. Recovering storage using Windows Update

1. Launch Windows PowerShell with administrator rights. To do this, open the Start menu or home screen and click on the “Search” icon. In the search box we write “PowerShell”. Right-click on “Windows PowerShell” and select “Run as administrator” or “Run as administrator”.

2. In the window that opens, write

Dism /Online /Cleanup-Image /RestoreHealth

and wait. If the storage is intact or it was restored using Windows Update, you will see the following picture.

If Image Health State: Healthy - everything is fine. Reboot the computer and try SFC /SCANNOW again.

4.2. Restoring storage using an image

If we have problems with Windows Update, then this method will do.

1. Download the original Windows 8/8.1 image of the same bit size as your system. How to find out the bit depth of the installed system - .

2. Connect or mount the downloaded image. Right-click on the image and select “Connect” or “Mount”.

3. In the command line with administrator rights, we look at what editions there are in the image with the command

Dism /Get-WimInfo /WimFile:F:\sources\install.wim

I have 2 editions in my image. It’s hard to understand which one I need based on these distinctive signs. Let's use the first one. If it doesn’t work, the second one.

4. Launch Windows PowerShell with administrator rights and set the command

Repair-WindowsImage -Online -RestoreHealth -Source F:\sources\install.wim:1

where F is the drive letter to which we connected the image, 1 is the Windows edition number in the image.

5. Recovering system files manually

If using the sfc utility it was not possible to recover damaged files, you need to try to do it manually. In this case, you need to additionally run the command

findstr /c:"" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

Findstr/c: ""%Windir%\Logs\CBS\cbs.log>sfcdetails.txt

and carefully study the file sfcdetails.txt on your desktop or %windir%\Logs\CBS\.

It should be something similar to the picture below.

After the name of the damaged file is known (Accessibility.dll), we look for it on another computer with the same system as yours. If this is not an option, then I would download the original Windows image and install it on the virtual machine. I found the file I needed and copied it to a bootable or installation flash drive. Then, from this installation flash drive, I booted into the recovery environment and launched the command line. From the command line I would open notepad. I opened the menu File > Open - and now I have an almost full-fledged explorer. We copy and replace the working file from the flash drive, reboot and everything should work.

If the option of installing a virtual machine does not suit you, then you can include the install.wim file in the folder. Then go to this folder and copy the necessary files.

1. Create a folder. For example, “Win8.1Pro” in the root of drive D.

2. Copy the install.wim file to the root of drive D.

3. Mount the install.wim file into the created folder.

Dism /Mount-Wim /Index:1 /WimFile:D:\install.wim /MountDir:D:\Win8.1Pro

Go to the created folder and copy the necessary files.

Disable the image

Dism /Unmount-Wim /MountDir:D:\Win8.1Pro /Discard
