Windows 11 compatibility checker to know my computer compatible with Windows 11?

Don’t rely only on the official Windows 11 compatibility checker tool, because it often gives a very simple pass-or-fail result without explaining the real reason clearly. In many cases, it just says the PC does not meet Windows 11 requirements, but it does not provide enough useful details for fixing the issue.

A better option is to check the hardware manually, including TPM 2.0, Secure Boot, UEFI boot mode, CPU model, RAM, and storage space. Sometimes the computer is actually compatible, but TPM or Secure Boot is disabled in BIOS, so the checker may make the situation look worse than it is.

For a clearer report, tools like WhyNotWin11 can be more helpful because they show which specific requirement failed. This makes it easier to decide whether the PC can be fixed through BIOS settings, needs a hardware upgrade, or requires another installation method.
