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.

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

The Health report starts off by showing you the last time a Device Health scan was run. The time displayed should be basically the current time, as Windows Security tries to run a Device Healthscan when you open the Device performance & health page.

Beyond the time of last scan you'll see the status of the key areas that Device Health monitors:

• Storage capacity - Is your system running low on disk space?

• Apps and software - Is any of your software failing, or in need of an update?

• Battery life- Is anything putting an extra strain on your PC's battery?You might not see this on on a desktop PC that is always plugged in.

• Windows Time service - Having your system set to the correct time is important for a lot of system processes. Windows Time service automatically synchronizes your system clock to an internet-based time service so your system time is always correct. If this service is off, or failing, Device performance & health will let you know so you can fix it.
