Going back from Windows 11 to a previous version (such as Windows 10 or Windows 7) is only supported for a limited time after the upgrade, typically 10 days. After that period, Windows automatically removes the files needed to roll back (mainly the Windows.old and $windows.~bt folders) to free up disk space.
If more than 10 days have passed since the upgrade and the Go back option is no longer shown under Settings > System > Recovery, it is not possible to use the built‑in rollback feature to return to the previous version.
To check (and what it means):
- Open Settings > System > Recovery.
- Under Recovery options, look for Go back.
- If Go back is present, it can still be used to return to the previous version.
- If Go back is missing or disabled, the rollback is no longer possible via this method because the required files have been removed.
Also note:
- Ten days after upgrading, the previous Windows installation is automatically deleted.
- If the previous version was manually deleted earlier via Settings > System > Storage > Temporary files by removing Previous version of Windows, rollback cannot be undone.
At this point, returning to Windows 7 would require a separate clean installation using original media and license (not covered by the rollback feature).
