    Run Microsoft's free PC Health Check. PCs from 2018 on usually pass, and a TPM or Secure Boot failure can often be fixed in the BIOS.

  • Windows 11 24H2 support ended. How do I update?

    Check your version with winver. If it says 24H2, install version 26H2 from Windows Update, or install it by hand on an unsupported PC.
