After you upgrade to Windows 11/10 you may notice two folders on your System or C Drive named $Windows.~BT and $Windows.~WS. These folders are hidden and are created by Windows, during the upgrade process. To see them, open Folder Options, and set Windows to show hidden and operating system files and folders. You will then be able to see them. These $Windows.~BT, $Windows.~WS and Windows.old folders are required by the system to perform the rollback operation. After 10 days, Windows 11/10 automatically deletes these folders during Automatic Maintenance. After 10 days, you may not see the option to Rollback in the Settings app or you may receive a message We’re sorry, but you can’t go back.
Roll back Windows 11/10 after 10 days
1] Rename these system folders
What you can do is rename these folders, as soon as you upgrade, and definitely before the 10-day period. Rename the following folders:
$Windows.~BT to say Bak-$Windows.~BT$Windows.~WS to Bak-$Windows.~WSWindows.old to Bak- Windows.old
When you do this, Windows 11/10 will not be able to delete these folders as you will have changed their names. If you decide to roll back after 10 days, rename these folders back to their original names and visit Settings > Update & Security > Recovery to Go back to Windows 8.1 or Windows 7. If you wish, you may also backup these 3 folders to an external drive with their original names. If you do feel the need, you should now be able to roll back even after 30 days. But then you will have to back up your latest data before you carry out the rollback operation.
2] Using PowerShell
Open an elevated instance of PowerShell and run the following command: If Windows.old folder is still present on your system, the number of days remaining for rollback will be displayed. If you see the following message then it means that the folder has already been deleted and there is nothing you can do: If Windows.old folder is still present on your system then do the following to extend the period to Go back to the earlier version, execute the following command: This will enable the period by 60 days. You can set 30 days or 60 days as per your requirement.
3] Using Registry Editor
If Windows.old folder is still present on your system then, open Registry Editor and navigate to the following key: Double-click on UninstallWindow and set the base to Decimal. Finally set the value to a number between 2 and 60. to extend by 2 months, set it at 60.
4] Clean Install Windows
If the Windows.old folder has been deleted, then there is only one method you can use to roll back to Windows 10 or any other version from Windows 11 – by clean or fresh installation. If you do not like the new operating system due to any reason, there is always another way to revert the change. For that, you need to download the ISO from the Microsoft website, create a bootable USB drive, and start the installation.
