A repair reinstall is a good option if you are having minor problems with Windows, such as software errors or performance issues. It will not delete your personal files or settings.
A clean install is a good option if you are having major problems with Windows, such as a virus infection or a corrupted operating system. It will delete all of your personal files and settings, so make sure to back them up first.
Here are some things to keep in mind when reinstalling Windows:
