Good health, my dear readers, brothers in computer science, as well as just guests of the site.

Yesterday I updated the operating system and could not boot from it. The fact is pedal, but quite solvable. After digging into the essence and causes of the problem, I found a way out. Therefore, today I will tell you what to do if windows 10 does not load after the update. We read carefully and remember!

What could cause this to happen?

There can be many factors like consequences and causes. We caught a virus (in this case, Comodo Internet Security will help), the update got up crookedly, the app store does not work, and much more. It is possible that the registry structure is simply damaged, which is why Windows simply cannot find boot sectors... Monitoring the stability of work will help prevent this situation. personal computer and a couple of helper programs.

For example, SS Cleaner... Ideal for users with minimal computer knowledge. Also, it is fine and - Reg Organizer... Also excellent software that will help you clean and configure the system.

It often happens that the update package comes out rather crude, therefore, due to a conflict with any of the drivers, the operating system may slow down, for example, the computer hangs on the screen saver. This is quite fixable, and we will consider examples of solving this problem below.

It is important to understand that any service packs and patches need to be downloaded only from the Microsoft website. Otherwise, you can completely spoil the installed graphical shell with low-quality content, to which, most likely, an inexperienced programmer, or even a hacker, has had a hand in it, which is even worse. Since it can hurt yourself important aspect- security.

What to do if the laptop freezes on the screen saver?

Initially, I would like to warn you right away. In the tenth Windows, the installation of updates is slow. If home screen launch operating system hangs for 2-3 minutes. This does not mean that the system is slowing down. Perhaps at this time, the tuning process is underway installed files and script bases. It can even take up to 10 minutes, depending on the size of the update itself. So it's better to wait. And if after this time the OS does not react in any way. Then you can deal with this problem.

If the laptop hangs on the screen saver, we need to roll back to a stable version.

I want to warn you right away that this method is not a panacea and it cannot help fix the whole problem with Windows at once. It only helps to fix the registry key. HKEY_LOCAL_MACHINE \ System \ CurrentControlSet... The boot menu of the last working configuration in latest version There is no operating system by the standard, but this item can be added.

We go to start, and run the line, type the command regedit.

The registry will open, we need to move to the section HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Configuration Manager... Here I will draw your attention to the parameter called BackupCount. He is responsible for how many times the system will save its state for rollback. According to the standard, there is only one, but you can change this figure yourself.

Now we go, as shown in the figure below, to the OS configuration manager. There you need to create a subsection. It should be called like this - LastKnownGood... In it, you need to create a parameter called - DWORD, make no mistake with the name. Set it to Enable.

This should also help if you get a blue screen after updating.

How to restore the system more correctly?

It happens that after installing the drivers, a black screen appears. A simple rollback will not help here, since the software part of the operating system is affected. you need to fully recover. This can be done in 5 different ways.

First... We go to the start menu, there we go to the parameters of our system and select " System protection».

Now you need to choose restoration of state with control point and press Further... A time plate will appear, in which you need to select the earliest point. Click it and restore it. At the same time, we will not lose files and will not have to go into the BIOS.

Second... A more radical method. It is based on resetting Windows to the original factory settings. It's like reinstalling, however, you won't need to copy and then restore files. The OS won't erase them. We go to the parameters of our laptop, then to the update and security section. Then we click on the restore line and select - return the computer to its original state.

Third way which uses file backup. Suitable when error 1607 appears. The latest version of the operating system has the ability to copy virtually all files for recovery. If necessary, they can be extracted and delivered as the main version of the software, thereby solving problems with new versions. But in this case, you will need to enable a feature called file history. You will also need an external drive - a USB flash drive or hard drive. We go to the parameters of our computer and open the section recovery and safety.

On the left side, in the menu, select archiving service... Now in right side you need to click on the plus sign and select chapter external storage , to which the data will be saved after copying.

If everything is completed and carried out correctly, then a switch will appear. It should be blue to indicate that the feature is enabled.

All now selected files that can be configured manually will be compressed and sent to an external device.

Fourth. Using a recovery drive. An extremely useful method, although it takes a lot of time. Will help with incorrect installation video card drivers. It will also help if the mouse on the laptop does not work. So, we insert a clean USB flash drive into our USB port. Next, we go to the start menu and there in the search bar we type the words - recovery disk. A section for creating one will appear.

The same can be done by pressing the key with the image of the Windows icon and the K (R English) key.

A window will appear with a description of why, in principle, such a chip is needed. We need to click the checkmark at the bottom and click the next button.

I would like to warn you right away that you need a flash drive at least 4 gigabytes. This is due to the fact that the tenth Windows is quite large in itself and the hard with recovery data will be quite weighty. This will be written in the next window. If everything is in order, the operating system will find the media itself and delete all data from it.

Next, the formatting of the flash drive will begin. It will take no more than 5 minutes. Next, there will be copying files. Here you will have to wait from 10 to 30 minutes.

If everything is fine, then you will see a sign like this.

If you get a black screen, or the key f8 does not work does not work, you can use this recovery disc. Just boot from it and select the very first icon from the top left.

Fifth... Usage installation disk... If you don't have one, I'll explain how to do it. We take a USB flash drive of 8 or more gigabytes. Copy everything required files and format it. Downloading the image operating system and check it for viruses using AVG AntiVirus Free.

A from here the UltraISO program. Next, install it and open it. Then click here.

Problems with updates can definitely arise at inopportune moments. Moreover, there are a number of reasons for this, so we advise you to take a closer look at the manual!


Today this software a little outdated. However, the popularity of the OS in question is still high. This article will tell you why Windows 7 won't update through Windows Update and how to fix the problem. There are a number of methods below.


Why updates are needed?

But first, you need to understand what these updates are for and what role they play for the user:

  • the product ensures the integrity and security of the OS;
  • the update provides compatibility with advanced machine parts;
  • software optimizes the program code;
  • fix improves the performance and multitasking of the OS.


What updates are there?

All software components are divided into several types:

  • important;
  • recommended;
  • optional;
  • other updates.

Important updates related to security Windows systems... It is recommended to install such packages from the moment they appear in notifications. Recommended components will improve the performance of your PC. The optional components include various drivers or updated software from developers. Others include those components that are not included in the above.

The OS distribution will not be reconstructed in the future, since Win 8 was released, and then 10. Developers will only support a special set of tools. The fans of the presented version have a lot of time left.


What is the reason for not installing updates to the OS?

Today, this may be due to the following reasons. Before doing anything, it is imperative to leave the opportunity Reserve copy data followed by a system restore point. Otherwise, the system may not stand up and the user will lose important data. That's why:

  • make a point to rollback the OS;
  • or create an image for backup using native tools - Win 7 archiver;
  • or use third-party software and create a similar copy in it.

Incorrect installation

Often incorrect installation lies in the error starting "Update Services". To enter the settings, just start the "Start" menu and register - "Services", after which a dialog box with the configuration of the parameters will pop up.


The dialog box displays a list of local OS tools. In the list, we will find "Windows Update". The list is displayed in alphabetical order, which means that the required element will be located at the very bottom. Click twice.


In some cases, the service tool is launched in offline... It also happens that the problem depends on the launch itself. It is worth checking if the service is running. This is most often observed on illegal (pirated copy) builds of the Win 7 distribution kit. Soft makers turn off the service on purpose. So let's make sure the local tool is enabled. If not, then turn it on.


The included OS updates application should be turned off.


Without leaving the dialog box with properties, press the Win + R combination on the keyboard, after which the Run system window will pop up, where we will enter: SoftwareDistribution and click OK.


The OS explorer will start with a subsystem folder "SoftwareDistribution" from which you will need to delete all existing folders and files.


Now let's go to the window with configuration options for local Win 7 tools and restart this item again.


After this operation, you will need to restart your PC and go to the "Update Center".


When the working window opens, download the updates and install. To quickly enter the configuration settings, you will need to open the "Start" menu and enter the desired service name in the search. In the dialog box, select the "Check for updates" option.


Install the required update package by clicking on the parameter of the same name.


When you only need to install special updates, then you have to click on the "Important updates" option.


Among the expanded list, check the boxes that we need.


Upon completion, we return to the initial window of the service and enable the installation parameter.


Errors downloading updates

One of the most common problems with updating Win 7 is failure during download to PC. This happens because the files are located and loaded into the OS cache. If the download fails, the installation process will be impossible. It should be noted that at the stage of downloading files, the update package will not be able to be overwritten. Initially, you will need to uninstall the disk space containing the cache, which stores the erroneous updates, and only then download the components.

To clear the cache, let's open a command prompt. In the search dialog box of the "Start" menu, enter the corresponding query - "Command line". Then, we will call the context menu and run it with administrator rights.


In line Windows commands you must enter the following combinations:

net stop wuauserv
ren% windir% \ SoftwareDistribution SoftwareDistribution.OLD
net start wuauserv



Click "Ok". After the cache is cleared, let's proceed to the system update, after restarting the PC.


Errors in the system registry

Most often, errors during the installation of OS updates occur due to a failure - 80070308. This happens due to the fault of the system registry. To return the system to its original appearance in the registry, you should make a number of edits. Press Win + R. The Run dialog box will pop up. In the field, enter: regedit and click "OK".


Go to the HKEY_LOCAL_MACHINE section and select the COMPONENTS subfolder in which we delete the PendingRequired. To delete a system file, open the context menu by clicking the right mouse button.


After the operation, restart the PC and install the updates manually.


Fix It - Automatically fix OS problems

To make it easier for users to troubleshoot such problems, Microsoft has developed a special software Fix It. It is in automatic mode will eliminate all possible errors with the OS. The utility can be downloaded from the link below.


Let's run the program installation file. The software will build an OS restore point on its own. After the listed operations, detection and elimination of system errors will start. After the program is running, close the utility and try to install the updates again.


What to do if there is no Internet access and the connection to the Microsoft site is blocked by an antivirus or a firewall?

If there is no Internet connection, which is usually a problem with proxy servers or the absence of the Internet itself, the download of updates will not start. If the problem lies in the antivirus or firewall, then at the time of installation, they should be disabled and manually installed the appropriate updates.


Inability to update due to lack of memory

Regularly the impossibility of installing updates for the Windows 7 operating system is the lack of free disk space on the hard disk of a personal computer or laptop. It should be borne in mind that most often the average volume of updates is up to 5 gigabytes. Before downloading and installing, you will need to free up the occupied disk space on the C drive and repeat the whole process again.


Long search for updates

Recently, when installing a clean image of Win 7 OS, it takes a long time to search for updates. In this case, no errors are observed. The problem is solved as follows:

  • install Microsoft Fix It and reboot;
  • restart the PC and install KB3102810 (links are given below!);
  • reboot again - everything should be fine.

This may be the reason why Windows 7 is not updated through the OS update center. This concludes the entire troubleshooting step. We will be glad if the information helped you. You can rate the article and write a comment! Share your advice with your friends. Thanks!
