Track your device performance and health in Windows Security

To help you keep your device secure, Windows Security monitors your device for security issues and provides a health report, which appears on the Device performance & health page. The Health report alerts you to common issues with your system and offers recommendations to remedy them. For more info on Windows Security, including how to turn Microsoft Defender Antivirus protection on or off, see Stay proteced with Windows Security.

View the Health report for your device in Windows Security

  1. In the search box on the taskbar, type Windows Security, and then select it from the results.

  2. Select Device performance & health to view the Health report. What you see in this report will vary, depending on your Windows version, device, permissions, and the issues that are found.

Note: If your device is part of an organization, your administrator may not have granted you permission to view Device performance & health.

If you meet system requirements, you'll also see the Fresh start option, which helps you refresh your device by reinstalling and updating Windows 10. Fresh start can be useful if your device has performance issues, if the memory is full, or if you have too many unused apps. Using Fresh start, you can refresh your PC without losing your settings or your personal files and photos. Fresh start can improve your device's startup and shutdown process, memory usage, browsing, battery life, and the performance for Microsoft Store apps.

To see which version of Windows you're running, in the search box on the taskbar, type winver, then select it from the results.

Here are some other options you can try before using Fresh start:

Note: If you're preparing to sell or donate a device, you'll need to wipe the device instead. This is also known as a factory reset. See the Reset your PC section in Recovery options in Windows 10.

Warning: 

  • Fresh start removes third-party antivirus software and all apps that don't come standard with Windows. This includes Microsoft apps such as Office, any desktop apps that came preinstalled on your device, and any Windows desktop apps, such as your device manufacturer's apps, support apps, and drivers. It keeps only Microsoft Store apps that your manufacturer installed.

  • You won't be able to recover the apps that are removed. You'll need to manually reinstall them. Once Fresh start is done, double-click the Removed Apps icon on your desktop to see a list of the apps that were removed.

  • You may lose your digital licenses, digital content associated with apps, or other digital entitlements for apps, which may impact your ability to use apps or app-related content that you paid for.

Use Fresh start to install a clean version of Windows 10 (Version 1909 and earlier)

Notes: 

  • Fresh start is available for Windows 10 versions prior to 2004. For version 2004 and after, Fresh start functionality has been moved to Reset this PC. To reset your PC, go to Start  > Settings  > Update & Security   > Recovery  > Reset this PC > Get Started. Then select Keep my files, choose cloud or local, change your settings, and set Restore preinstalled apps? to No

  • If you don't see the option to Restore preinstalled apps, it means your PC doesn't have preinstalled apps configured and won't restore apps from your PC manufacurer.

  1. Verify that you meet the system requirements. To access Fresh start, your device must be running Windows 10 Home or Windows 10 Pro, and you must be signed in as an administrator. Learn more about Windows 10 specificationsCreate a local user or administrator account in Windows 10.

  2. Gather all reinstallation media (such as CDs), product keys, license or sign-in information, or anything else you'll need to manually reinstall and reactivate the apps or app-related content you want to keep using. For Microsoft apps, see Find your Microsoft downloads and product keys.

  3. (Optional) Back up your files. We recommend this precaution, even though Fresh start keeps your data intact.

  4. In the search box on the taskbar, type Windows Security, and then select it from the results.

  5. Select Device performance & health.

  6. Under Fresh start, select Additional info, and then select Get Started to start the process.

When Fresh start is done, you can reinstall any apps you want to keep using. To see a list of the apps that were removed, go to your desktop and double-click the Removed Apps icon you'll find there.
