Track your device and performance health in Windows Security

Applies to: Security

Device performance & health in Windows Security helps you keep your devices refreshed and up to date with the latest version of Windows 10. Device health advisor monitors your device and provides you with information and recommendations in a Health report to address common issues with your storage capacity, device drivers, battery life, or Windows Update.

Device performance & health also includes Fresh start, which is a feature that helps you refresh your device by reinstalling and updating Windows—for example, if your device has performance issues or you have too many unnecessary apps.

Device performance and health in Windows Security

In Device performance & health, you’ll have the following features available:

  • Health report. Tells you if there are any issues impacting the device health, such as storage capacity, devices, battery, or ability to update to the most recent version of Windows. It also provides recommendations about steps you can take to resolve these issues.
  • Windows Update. Tells you whether you’re up to date with your versions of Windows, and—if you aren’t—alerts you with details about specific issues that could be causing your device to not be up to date.
  • Storage capacity. Checks if your device has enough space to update Windows, and alerts you if there’s a recommended action.
  • Device driver. Checks the drivers on your device to see if they’re functioning properly, and alerts you if there’s a recommended action.
  • Battery life. Checks the impact of the brightness level and sleep settings on the battery life, and alerts you if there is a recommended action to maximize your battery life.
  • Fresh start. Lets you perform a clean reinstallation and update of Windows while keeping your personal data and most Windows settings intact. Fresh start will remove most of your apps from your device. In some cases, a clean installation may improve your device's startup and shutdown experience, memory usage, Microsoft Store apps performance, browsing experience, and battery life.

To use Fresh start, select Additional info, and then select Get Started. You can also see the last time you ran Fresh start and a list of the apps that were removed so you know which apps to reinstall.
