This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app or driver, and when you create a restore point manually. Restoring won't affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.

    • If you're not seeing any restore points, it might be because system protection isn't turned on. Here's how to check:

      1. In the search box on the taskbar, type control panel, and then choose it from the list of results.

      2. In the Control Panel search box, type recovery.

      3. Select Recovery > Configure System Restore > Configure and see if theTurn on system protection option is selected.

        • If the Turn on system protection option is not selected, system protection isn't turned on and there aren't any restore points. In this scenario, you won't be able to recovery your PC using a system restore point and will need to use one of the other recovery options listed on this page.

        • If the Turn on system protection option is selected, continue with step 6.

  6. You'll see a list of items that will be deleted if you remove this restore point. If you're OK with the deletions, select Close> Next > Finish.

  • 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.

Refresh, reset, or restore

Select any of the following for more detailed info.

If your PC isn't performing as well as it once did, and you don't know why, you can refresh your PC without deleting any of your personal files or changing your settings.

Note:If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, refreshing your PC will restore Windows 8. You'll need to upgrade to Windows 8.1 after the refresh has finished.

Warning:Apps you installed from websites and DVDs will be removed. Apps that came with your PC and apps you installed from Microsoft Store will be reinstalled. Windows puts a list of removed apps on your desktop after refreshing your PC.

To refresh your PC

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, selectSettings, and then select Change PC settings.)

  2. Tap or select Update and recovery, and then tap or select Recovery.

  3. Under Refresh your PC without affecting your files, tap or select Get started.

  4. Follow the instructions on the screen.

If you want to recycle your PC, give it away, or start over with it, you can reset it completely. This removes everything and reinstalls Windows.

Note:If you upgraded your PC from Windows 8 to Windows 8.1 and your PC has a Windows 8 recovery partition, resetting your PC will restore Windows 8. You'll need to upgrade to Windows 8.1 after the reset has finished.

Warning:All of your personal files will be deleted and your settings will be reset. All apps that you installed will be removed. Only apps that came with your PC will be reinstalled.

To reset your PC

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, select Settings, and then select Change PC settings.)

  2. Tap or select Update and recovery, and then tap or select Recovery.

  3. Under Remove everything and reinstall Windows, tap or select Get started.

  4. Follow the instructions on the screen.

Note:You'll be asked to choose whether you want to erase data quickly or thoroughly. If you choose to erase data quickly, some data might be recoverable using special software. If you choose to erase data thoroughly, this will take longer but it makes recovering data less likely.

If you think an app or driver that you recently installed caused problems with your PC, you can restore Windows back to an earlier point in time, called a restore point. System Restore doesn't change your personal files, but it might remove recently installed apps and drivers.

Notes:

  • System Restore isn't available for Windows RT 8.1.

  • Windows automatically creates a restore point when you install desktop apps and new Windows updates, if the last restore point is older than 7 days. You can also create a restore point manually at any time.

To restore your PC to an earlier point in time

  1. Swipe in from the right edge of the screen, and then tap Search.
    (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.)

  2. Enter Control Panel in the search box, and tap or select Control Panel.

  3. Enter Recovery in the Control Panel search box, and then tap or select Recovery.

  4. Tap or select Open System Restore and then follow the instructions.

If you need additional help refreshing, resetting, or restoring your PC, check out the Repair and Recovery community pages in the Windows forum for solutions that other people have found for problems they've experienced.
