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.

At a Glance

Check that System Restore is turned on

~27s

Click the Start button, type "Create a restore point," and press Enter. A window called "System Properties" opens to the "System Protection" tab. Look at the list of drives — your main C: drive should show "Protection: On." If it says "Off," click "Configure" and select "Turn on system protection," then click OK.

Quick Tip

Quick Tip: Set the disk space usage slider to about 5–10% of your drive size. This allows Windows to keep several restore points going back a few weeks.

Create a restore point right now

~20s

In the same System Properties window, click the "Create" button at the bottom. Type a short description — something like "Before installing new software" or today's date. Click "Create" again. Windows will create the restore point in less than a minute and confirm when it is done. This is a good habit before any major software install.

Open System Restore when you need it

~15s

When you need to undo a change, click the Start button, type "Create a restore point," and press Enter. In the System Properties window, click "System Restore." A wizard will guide you through the process. Click "Next" on the first screen.

Choose a restore point

~28s

Windows shows you a list of available restore points with their date, time, and a description of what created them. Choose a restore point from before your problem started. If you do not see the one you want, check the box that says "Show more restore points." Click "Scan for affected programs" to see what software will be removed by the restore.

Warning

Any programs installed after the restore point date will be uninstalled. Your personal files will not be affected, but you may need to reinstall some software afterward.

Confirm and run the restore

~29s

After selecting your restore point, click "Next" and then "Finish." Windows will ask you to confirm — click "Yes." Your computer will restart automatically and begin the restore process. This takes 15–30 minutes. Do not turn off your computer during this time. When finished, Windows will start up normally and show a message confirming the restore was successful.

Quick Tip

Quick Tip: If the restore did not fix the problem, you can undo it. Go back to System Restore and choose "Undo System Restore" to return to where you were before.

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.
