System Restore: Undo Windows Changes When Something Goes Wrong
System Restore lets you roll Windows back to an earlier point in time — before a bad update or software install caused a problem — without deleting your files.

System Restore is a recovery tool built into Windows that can rewind your Windows settings and installed programs back to an earlier state — called a "restore point" — without touching your personal files. If you install a program that causes problems, receive a Windows update that breaks something, or make a change to settings that you cannot undo, System Restore can bring your PC back to how it was before the problem started.
It is important to understand what System Restore does and does not do. It undoes changes to Windows system files, installed programs, and Windows settings. It does not delete, move, or affect your personal files — your documents, photos, music, and downloads stay exactly where they are. This makes it a safe first step when Windows is misbehaving.
Windows creates restore points automatically at regular intervals and before major changes like Windows updates. You can also create restore points manually at any time — and it is a good habit to do so before installing new software or making changes to Windows settings you are uncertain about.
System Restore is not a substitute for a full file backup. It only preserves Windows system data, not your personal files. If your hard drive fails completely, System Restore cannot help. That is why File History and external drive backups are also important.
If Windows is so broken that it will not start up normally, you can still access System Restore from the Windows Recovery Environment — a special startup mode. To get there, restart your computer and press F11 (or sometimes F8) during startup, or go to Settings > Recovery > Advanced startup.
