Sometimes when you upgrade to a newer version of Windows 11, the setup process saves a copy of the previous version in the “Windows old” folder.
This is part of a safety mechanism in case the upgrade process goes wrong, the system will use the “Windows old” folder to undo the changes, and if the upgrade completes successfully the backup copy of the previous version will remain for the option to roll back if the new installation starts causing bugs and issues.
This is a useful feature but if your device works perfectly after the upgrade, you can safely delete the previous installation files to reclaim storage space. In this guide, we will show you how to safely delete the Windows old folder on Windows 11.
