Deleting most of the file categories that appear in Disk Cleanup is perfectly safe. But, it’s recommended that you don’t delete the Windows ESD installation files if the option shows up since these are critical to reset the OS. This will present you with the option of uninstalling the latest Quality Update or the latest Feature Update, which should allow you to boot back into Windows safely again. It doesn’t present you with a list of recent updates the way it does in Control Panel, so we still recommend trying the steps in the above sections first. If all else fails, this recovery option is a last-ditch effort.

The Windows ESD installation files are related to the feature of “Reset this PC”. If you delete them, “Reset this PC” will not work normally. If you want to factory reset your computer, you need to use a Windows installation medium instead. We recommend not deleting this, unless you desperately need the few gigabytes in hard disk space. Deleting this will make your life harder if you ever want to use the “reset your PC” feature in the future.
Unfortunately, you might not have a restore point from immediately before you made modifications, even for less extreme resets. Windows allows you to manually establish a restore point, but if you’re already having issues, it won’t help. You can either wipe everything clean or start again, and you can just reinstall Windows and maintain your existing files.
However, below lists the common reasons for deleting a user profile. Then erase the .bak and press Enter to keep the modification. In cases like this, the Windows auto-login option can be used to automatically log you into your computer without going through the Windows login page each time. Unfortunately, some Windows 11 users have reported that after they activated auto-login on their PC, it stopped working.
