Tip: How to resume the Windows 10 installation media creation process

Windows users can run Microsoft's Media Creation tool to create a Windows 10 ISO image or copy the installation files required by the operating system to a USB Flash drive.

Since the download has a size of several Gigabytes, it can happen that it stops at one point during operation, or that the operation stops at the processing phase.

If you then run the tool again to complete the process, you will notice that the download starts from zero instead of resuming from the position the previous operation stopped at.

This may not be a problem for users no high speed Internet connections, but if your Internet is unreliable or slow, you may not want to go through the whole ordeal again especially since there is a chance that the operation may stop again at one point in time.

While there is no option to resume the download itself, it is at least possible to resume the creation of the installation media if the download completed successfully. It is hidden from sight however and not available in the tool's interface.

If you run the tool, it creates two directories on your main partition: $WINDOWS.~BT and $Windows.~WS. These folders contain the installation files, and an option to resume the creation process if it fails. Please note that these folders get populated during download, and that the download needs to complete successfully for all files to become available.

windows-10 resume installation media

Open C:\$Windows.~WS\Sources\Windows\sources on the system and locate the file setupprep.exe. When you start it, the process will resume the last operation instead of starting completely anew. This means that it will resume the creation of the media using the downloaded setup files.

Tip: These directories are created even if you select to create an ISO image or copy the files to USB Flash drives.  This means that the files (may) remain on the drive even after the successful completion of the process. You may want to delete them after you have created installation media for Windows 10 as they take up Gigabytes of storage space.

Please note that these folders may be hidden by default. You need to make them visible first using the folder options. On Windows 7, you simply click organize > folder and search options, switch to View, and select "show hidden files, folders and drives".

The missing download resume option is problematic, especially for users with slow or unreliable Internet connections. No workaround or alternative is available right now that would improve the experience for users.

    The $WINDOWS.~BT and $Windows.~WS folders are left on the computer after the media creation ends.
    The $Windows.~WS folder had a lot of files in it and is nearly 6 GB.
    Can the folders be safely removed?

      Yes, if you have created the media and don’t plan on creating a second one, you can remove them.

      They can be deleted using the Disk Cleanup Utility. After starting it click on the box that says “Clean up system files”. When the list comes up, check all boxes that have data listed. Scroll down to make sure you get them all. Once you give the OK, give it some time to complete. I ran it about an hour ago as I’m satisfied with Windows 10, as an upgrade from 8.1, and don’t plan to roll it back, ever.

      You should only delete it if you don’t play on downgrading. If you remove the folder, using Disk Cleanup, then you cannot restore the older version of Windows anymore.

      Actually that means your media creation tool have not completed downloading all files. There should be a file with extension .tmp in C:\$Windows.~WS\Sources. Use Proxifier software to have a track on network usage and downloads. It will show you svchost.exe is using your network which is responsible for downloading file for media creation tool. From there you can confirm that your download is still under process. Wait till the svchost.exe to dissappear in connection tab in Proxifier and check folder again.

      There does not seem to be an option right now to resume the download itself. I’m not sure why Microsoft made the decision to not support resume.

    Can I use the file Install.esd in $WINDOWS.~BT folder to create a installation media? I’ve already upgraded to Windows 10 and the install files are still in this folder. I’m asking this ’cause I have slow connection and don’t want to download all the files again with Microsoft’s Media Creation Tool.

    Note: If you have unreliable network or need to pause download (by media creation tool) for some reasons, then you should “hibernate” instead of “shutdown” your PC without closing the media creation tool’s download window. When you restart your PC sometimes later, download Will resume. It’s time saving especially if you have frequent power cuts.
    I had upgraded to windows 10 through windows update and clean installed it following the above precaution.

    Hi,
    I have downloaded the win 10 update to 100%, but during installation it stopped and somehow got restarted. So I searched to use the downloaded file to resume it. Now I have only $Windows.~BT folder and not the other $Windows.~WS. Also there is no folder named windows in $Windows.~BT/sources/. Please suggest me something to I can resume.
    I have .tmp file in windows/softwaredistribution/download, of 2.7GB.

    Hi, i used media creation tool and chose upgrade pc to download windows 10. In the root folder you can see only $Windows.~BT because the $Windows.~WS folder is hidden. first you have to make sure that any folder in the root drive is not hidden. You can do this by folder properties option in organize tab as shown above. Now in the $Windows.~WS folder you find source folder if you don’t find the Windows folder that means your download is not complete. For the first time when i ran the media creation tool every thing was good till 96% of download but suddenly the window disappeared automatically. In this case what i did is; once again tried to run the media creation tool as an administrator but it’ll say something like ” set up tool didn’t download some important files”……… and then show…… ”the setup tool failed to……….reboot your pc and try again” . As instructed in the message i restarted my pc and tried to run the media creation tool again and again after rebooting my pc but the result was same. Doing that multiple times it finally ran again. I thought running the media creation tool again would delete all the previously downloaded files. And yes i saw no files in the $Windows.~WS folder for a while but all the previously downloaded files were vanished temporarily which showed up again. Then my download started again from 0% but this time some new files were downloaded.

    Hi! I’m using media creation tool and I’m worried that that my download might finish. It’s been 6hrs since I started the download an now the progress is stuck at 77% for about 45mins now. What should I do about this? Should I stop the program and follow the instructions in this tip?

    Hello dear. There is no sub folder named windows in the mentioned folder. Microsoft should have a solution. If they do not why they insist to download it through media creation tool. Anybody from Microsoft please either inform your superiors about the problem or at least mention that its not resumable so that user should be mentally ready that he would have waste lot of time and energy

      On your taskbar a white windows logo should appear and if not update your PC. Click on the logo an follow the instructions from there
      BTW what os are you using WinXp?WinVista?Win7?Win8RT?Win8?Win8.1?

    Hi
    I have a weird question which is kinda related and kinda unrelated also 😉
    I have dozen of different windows 10 Iso file which consisted of almost all of it’s editions till now. But I got aware that there’s still someway available to upgrade to windows 10 from 7 and get official and legal licenses. The problem is the mentioned windows 7 is on expensive metered and way too slow network connection (2G Mobile with limited data plan). And if I’m not wrong you can’t get to keep your license by upgrading from bootable DVD or USB ISO image.
    So my question basically is this:
    “Is there any way to force Microsoft Media Creation Tool to use a previously downloaded ISO as it’s source for files thus prevent it from huge bandwidth consumption??’
    Even 80 to 90 percent of download prevention is enough.
    Thank
