How to use the PC Health Check app
Applies to: Windows 10 and Windows 11
Last updated: September 18, 2026
- Install PC Health Check from the Microsoft Store if it is not already on the PC.
- Open it and select Check now under the Windows 11 requirement.
- Read each line that fails. TPM and Secure Boot can often be turned on in firmware. An unsupported processor cannot.
- Use the other tiles, such as backup and startup time, as hints. They do not replace Task Manager when you are chasing a slow app.
