Note
Returning Windows to original settings doesn’t completely delete everything on your computer. It deletes programs, but saves user files to the Windows.old folder on your hard disk, which you can browse to after the reinstall completes. However, you should still back up any user files before using this method. For example, if you have encrypted files, you might not be able to access them after installing Windows. If you’ve backed up your user files and then restored them after reinstalling Windows, you can delete the Windows.old folder.
