Before you start
- Back up important files first.
- If device encryption/BitLocker is enabled, make sure you have the recovery key before starting.
Try less destructive recovery first
For a PC that still starts, use troubleshooters, Windows Update, app repair, DISM/SFC, update removal or System Restore before resetting.
Open Reset this PC
Go to Settings > System > Recovery > Reset PC. If Windows will not boot, use WinRE > Troubleshoot > Reset this PC.
Choose Keep my files or Remove everything
Keep my files reinstalls Windows while preserving personal files, but it removes installed apps and resets settings. Remove everything also removes personal files.
Choose Cloud download or Local reinstall
Cloud download downloads a fresh Windows image; Local reinstall uses files already on the PC. Follow the review screen carefully before confirming.
Do not interrupt the reset
Windows can restart several times. Keep a laptop connected to power. If you are selling/giving away the PC, review the additional drive-cleaning options presented by Windows.
