Under normal conditions, for image creation deployment uses a .wim file. It can be created different methods, but it was as a wim-image and remains a wim-image. The same file is used not only for network installation, but also for writing to a bootable USB flash drive in order to install an operating system with all the necessary complex software... But recently I was preparing an image for one office that uses Windows 10 LTSB. I did not immediately notice the catch, since I was using a computer on which the reference system was already installed. The system was prepared to work using WDS (Windows Deployment Services) and everything went as planned. But when I started preparing a bootable USB flash drive for offline installation of the operating system, then the dancing with a rake began. There was simply no file in the right place in the ISO image install.wim... But in its place a file was found install.esd... As it turned out, Microsoft developed new format image files in order to increase the compression ratio and support the ability to download the image over the Internet. For this, the compression ratio had to be increased. WIM images also support compression, but it is believed that an ESD image can have super strong compression and this will allow downloading an operating system update over the Internet.
I was wondering how much WIM and ESD compression are, but for now I won't waste time on such little things. Let's take the developers' word for it.
So, what should we do if an ESD disc was used. Actually, you won't have to do anything new. On the disk used to download the program imagex.exe... To work with an ESD image, you can use the program DISM.exe from the delivery of Windows ADK for Windows 10, do not confuse with Windows AIK. The Windows AIK also has DISM, but it can work exclusively with WIM images.
The entire creation procedure is similar to creating a disk with a WIM image:
- We create a bootable flash drive,
- install Windows,
- install required software,
- copy the required data,
- we prepare the OS with the program Sysprep,
- then we boot from the LiveCD or over the network,
- creating an ESD image,
- replace the file with the created image install.esd on a flash drive.
Of all these operations, only ESD image creation is unusual. To create an image, you need to copy the program to a LiveCD or a USB flash drive DISM.exe from the delivery of Windows ADK for Windows 10.
We go into the directory with DISM.exe and give the command:
Dism.exe / Capture-Image /ImageFile:D:\install.esd / CaptureDir: D: \ / Name: OrcinusCapture
Let me explain what he is responsible for:
Dism.exe - launch an executable file,
/ Capture-Image - command to create an image,
/ ImageFile: D: \ install.esd- the file into which the image will be packed,
/ CaptureDir: D: \- the disk on which the installed OS is located,
/ Name: OrcinusCapture - the name of the image, you can write whatever you want.
You can save the image to the disk from which the image is made. Or immediately copy it to a bootable USB flash drive. It doesn't matter.
That's it, now you need to copy the resulting ESD image to a bootable USB flash drive and you have your own distribution kit ready for installation.
When upgrading the Windows operating system to more new version, or assembly, a special image with the ESD extension is loaded, it contains the entire assembly of the system, intended for further updating, or installation on a clean system.
Today we will take a closer look at a way to convert an ESD file to an image. ISO disc which, in the future, can be used to write the system to disk, or to create bootable flash drive to later install Windows 10 from it.
Here we will use a tool that allows you to convert files of this kind, using the built-in system utility that allows you to work with such images - DISM. To make everything go automatically, additional utilities and a batch file will be used.
First step: Download the update and download the ESDtoISO utility
In our case, we took an update with assembly number 10166. It was located in the following directory: C: \ Windows \ SoftwareDistribution \ Downloa \ c31932a53b8bd06aedcff39a19. This folder contained a file whose name looked like this: 10166.0.150703-1818.fbl_impressive_CLIENTPRO_RET_x64fre_ru-ru.esd.
In other updates, assemblies with other versions could be located in other directories, for example:
C: \ Recoveryimage C: \ Windows \ SoftwareDistribution \ DeliveryOptimization C: \ $ Windows. ~ BT \ Sources
So, if you need a different assembly than the one described in this article, you will have to look desired file... The best way is to use Search in the system.
By the way, the file with the update can be renamed to any other convenient name, here it may come up install.esd.
Second step: Launch ESDtoISO
In this case, when choosing the first option, a file with a volume of 3931455488 bytes will be released. And if you choose the second option, then we will have a file with a volume of 3177324544 bytes.
When the conversion is over, the finished image will be located in this path: D: \ ESD \ ESDtoISO. Both the one and the other file will be able to fit for normal, classic. In any case, the output will be the usual ISO image, from which it will be possible, or a USB flash drive.
The difference in the size of the finished files is different ways compression. If you choose the second option, then during the installation process you will need to spend large quantity time for unpacking the data, as a result of which the installation itself can take ten minutes longer.
Format .ESD stands for Electronic Software Distribution. It is not a format in the usual sense of the word, but a technology that is intended to be disseminated. It is used to enable Microsoft software to be distributed electronically. Among the distributions, there is also an image of the Windows 10 operating system. If the .ESD format is used for distribution, then all programs that are presented in it will have a compressed form. If you download an image of a new operating system, it will be 35 percent larger than the Windows 10 file downloaded in .ESD format.
This technology is not yet widely used for the distribution of Microsoft products. So far, only those users who have access to the internal lines of the corporation can use it. Distributions in .ESD format are not intended for regular users. However, on the official Internet resource of Microsoft there are several programs in .ESD, which are located in open access.
Today there is a large number of questions about this format for the reason that users cannot understand why there are programs in the open access in the .ESD format, but they are almost impossible to download.
Initially, you need to go to the official website of Microsoft and download the ESD image of the Windows 10 operating system from there. There are direct links on it. It should be noted that the OS images will be in English.
If the user already has a downloaded Windows 10, then there is no need to download its ESD image. It can be found in the system folders of the operating system. It should simply be copied from one folder and transferred to another.
When the ESD image is loaded, you need to decrypt or unpack it. It should look like an ISO image. Such a procedure can be performed using the following programs: Decrypter, NLite, WinReducer Wim Converter. First you need to figure out how this procedure is carried out in the most simple-to-use Decrypter utility.
First you need to unpack the archive and save all its contents in the ESD-Decrypter folder.
This folder must also be copied from the system folders of the Windows 10 operating system and its ESD image.
Then you need to go to the folder and open the decrypt.cmd file there. Launch of this file must be done on behalf of the administrator.
Name In the Enter your Option column, you need to put the number 1.
After that, you need to press any button on the keyboard to go to the next step.
If we go to the ESD-Decrypter folder, we can notice that an ISO image file has appeared in it.
This file can be used to install the operating system at any time. It may also be required to create a bootable USB flash drive, or an installation disc.
If the user has computer device already available operating system, then you do not need to download from the site ESD image... It is located in the C: \ $ Windows. ~ BT \ Sources folder.

Currently operating Windows system 10 is a popular product. Its ISO image can be downloaded from the official Microsoft website. However, many users are interested in another ESD format. Programs 4.81 14
Or $ Windows. ~ BT, $ Windows. ~ WS. It turns out that the ESD folder also stores various temporary files that can restore the system if, for example, a critical error has occurred. But the question comes, is it possible to delete the ESD folder? I want to say that yes, you can. The folder stores recovery files, which weigh a lot and if you do not have a lot of hard disk space, then you should delete it.
Advice! I suggest that at first you do not delete this folder, as well as Windows.old and others, since if you are only recently using Windows 10, then you can test it for now. If everything suits you, then you can delete all unnecessary garbage. I recommend doing this by staff Windows tools Disk Cleanup.
So, if you have administrator rights, then go to the utility Disk Cleanup, you can enter it in the search box.
Now, in our field "Disks" need to choose system disk, usually it is (C :). Click OK.
We are waiting for the system to estimate the disk space that can be freed.
The following window will appear, in which you must click the button "Clear system files» ... Again, we are waiting for the estimated disk size.
We confirm actions by pressing a button "Delete files" and wait for the operation to be completed.
Once the temporary files are removed you can do some more. To do this, in the Disk Cleanup utility, go to the tab "Additionally" and where the point is System Restore and Shadow Copy push "Clear"... It is advisable to delete all control points, and leave the last so that you can return in case of something.
Actually, that's all. If you have any questions, ask them in the comments, let's try to figure it out.
