What is System Restore?

System Restore helps you restore your computer’s system files to an earlier point in time. It’s a way to undo system changes to your computer without affecting your personal files, such as e‑mail, documents, or photos.

Sometimes, the installation of a program or a driver can cause an unexpected change to your computer or cause Windows to behave unpredictably. Usually, uninstalling the program or driver corrects the problem. If uninstalling does not fix the problem, you can try restoring your computer’s system to an earlier date when everything worked correctly.

System Restore uses a feature called System Protection to regularly create and save restore points on your computer. These restore points contain information about registry settings and other system information that Windows uses. You can also create restore points manually.

Restore a driver to its previous version

You must be logged on as an administrator to perform these steps.

You might want to restore the driver software for a device to a previous version if you encounter problems with your computer or device after upgrading the driver software.

1. Click to open Device Manager.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2. Double-click the category containing your device driver, and then double-click the name of the device you want to restore to a previous driver version.

3. Click the Driver tab, and then click Roll Back Driver.

Start System Restore from a command prompt

You can start System Restore from a command prompt window if you cannot start your computer in any mode other than safe mode with command prompt.

1. Start your computer in safe mode with command prompt. For more information.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2. At the command prompt, type rstrui.exe, and then press ENTER.

   Note

• If you use System Restore when the computer is in safe mode, you cannot undo the restore operation. However, you can run System Restore again and choose a different restore point if one exists.

Undo System Restore

If you tried using System Restore to fix a problem but the problem remained or other problems were introduced, you can undo the restore operation. After you undo System Restore, you can try using a different restore point.

1. Click to open System Restore.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2. Click Undo System Restore, and then click Next.

3. Review your choices, and then click Finish.

   Your computer will restart. When finished, you’ll see a confirmation that the undo process is completed.

   Note

• If you use System Restore when the computer is in safe mode, you cannot undo the restore operation. However, you can run System Restore again and choose a different restore point if one exists.

Tips:

Windows starts but runs erratically or slowly

If Windows starts but runs erratically or slowly, try these options.

1. System Restore. System Restore can return your system files to a point in time before you noticed a problem. System Restore works without affecting documents, photos, or other personal files.

2. Last Known Good Configuration. This advanced startup option starts Windows using the registry settings and drivers that were in use the last time the computer started successfully.

3. Safe mode. If the Last Known Good Configuration option doesn’t work, you can use safe mode to try to identify and fix the problem. If your computer will only start in safe mode, recently installed hardware or programs might be causing the problem.

   In safe mode you can:

   • Disable a device. If a device that you recently added is causing problems, you can use Device Manager to disable the device.

   • Restore a driver. If you recently updated a driver and experienced problems, try undoing the update.

   • Run System Restore. You cannot undo the restore operation while running in safe mode, but you can run System Restore again and choose a different restore point (if one exists).

Windows does not start at all

In extreme cases where a serious error is preventing Windows from starting at all, try these options:

• Startup Repair. Startup Repair is a Windows recovery tool that can fix certain problems, such as missing or damaged system files, that might prevent Windows from starting. It is located on the Windows installation disc and, depending on your computer, might also be stored on your computer’s hard disk.

• Reinstall Windows. If your system has been severely damaged, you might need to reinstall Windows. A custom (clean) installation of Windows will permanently delete all of the files on your computer and reinstall Windows, so only use this option if all other recovery options have been unsuccessful. After the installation, you will need to reinstall your programs and restore your files from backup copies.
