Note
For information about this topic in Windows 10, see Recovery options in Windows 10.
If you're having problems with your PC, you can:
- Refresh your PC to reinstall Windows and keep your personal files and settings. Refresh also keeps the apps that came with your PC and the apps you installed from the Microsoft Store.
- Reset your PC to reinstall Windows but delete your files, settings, and apps—except for the apps that came with your PC.
- Restore your PC to undo recent system changes you've made.
If you're having trouble starting (booting) your PC, see Windows Startup Settings (including safe mode), and go to the “Get to Windows Startup Settings in the Windows Recovery Environment” section. 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.
Before you start to refresh or reset your PC
In most cases, once you start to refresh or reset your PC, it’ll finish on its own. However, if Windows needs missing files, you’ll be asked to insert recovery media, which is typically on a DVD disc or thumb drive. If that happens, what you’ll need depends on your PC.
If your PC came with Windows 8.1 or Windows RT 8.1, you’ll need the discs or thumb drive that came with your PC. Check the info that came with your PC to see if your PC manufacturer provided these discs or media. In some cases, you might have created them when you first set up your PC.
If you don’t have either of those, you can make them if you have a USB thumb drive of 16 GB or larger. Having a recovery drive can help you troubleshoot and fix problems with your PC, even if it won’t start. For more info, see Create a USB recovery drive.
If you upgraded your PC to Windows 8.1 or Windows RT 8.1 with a DVD, use that disc. If you don’t have Windows 8.1 or Windows RT 8.1 media, contact Microsoft Support.
