Windows 11 is Microsoft’s first new operating system in nearly six years. As the successor to Windows 10, it offers radical changes to the user interface and many innovative features to support a modern hybrid work environment and improve user productivity.

As for updates, Windows Update will optimize the update mechanism in Windows 11, and the cumulative update package will be 40 percent smaller than in Windows 10. Microsoft also promises to provide free updates to Windows 10 users.

However, not all Windows 10 computers are eligible for the upgrade – you must meet the minimum system requirements of Windows 11, or you’ll get a “This PC cannot run Windows 11” message during installation.

Why can’t I run Windows 11 on this PC?

  • Hardware specifications not met: Although Windows 11 hardware specifications are comparable to Windows 10, older systems may have runtime issues (especially systems with limited memory).
  • The legacy boot is preferred over UEFI: It appears that you can expect this error message if your current Windows 10 installation is configured to use legacy boot mode instead of UEFI (even if your system supports it).
  • TMP 2.0 is not supported or disabled: TPM 2.0 has become an industry standard and your computer should support it unless you have an outdated motherboard. Check if TMP 2.0 is supported on your system and enable Trusted Platform 2.0 in your BIOS or UEFI settings so that the error will not occur again.
  • Secure Boot is not supported or disabled: Secure Boot is supported on the vast majority of motherboards released in the last five years, but this security feature may be disabled in the BIOS or UEFI settings.
