How to read the result
A failed or unavailable check does not always mean the PC is permanently incompatible. TPM or Secure Boot may be supported but disabled in firmware. The report distinguishes a missing feature from a feature Windows could not read.
CPU compatibility
Processor eligibility can change with Microsoft's supported-processor policies. The detector reports the exact CPU model and treats final CPU-list confirmation separately rather than guessing.
Before upgrading
Back up important files and confirm compatibility using Microsoft's current Windows requirements before making firmware or operating-system changes.
