If you're having problems with your PC, you can try to refresh, reset, or restore it. Refreshing your PC reinstalls Windows and keeps your personal files and settings. It also keeps the apps that came with your PC and the apps you installed from the Windows Store. Resetting your PC reinstalls Windows but deletes your files, settings, and apps—except for the apps that came with your PC. Restoring your PC is a way to undo recent system changes you've made.
If you're having trouble starting (booting) your PC, see Windows Startup Settings (including safe mode). You can refresh, reset, or restore your PC from the Windows Recovery Environment.
If you want to back up and restore your personal files using File History, see Set up a drive for File History.
