Bypass Windows 11 Upgrade Assistant / Setup Hardware Checks (TPM, CPU, RAM)

This powerful app allows you to bypass TPM 2.0, unsupported CPU, and memory checks enforced by the Windows 11 Upgrade Assistant and setup.exe from Windows installation media. It eliminates common upgrade blocks such as:

  • This PC doesn't currently meet Windows 11 system requirements.
  • TPM 2.0 must be supported and enabled on this PC.
  • The processor isn't currently supported for Windows 11.

What It Does

  • Deletes legacy upgrade failure registry keys that may block future attempts.
  • Simulates hardware compatibility by setting known override values (e.g., TPM, RAM, Secure Boot).
  • Enables Microsoft's official upgrade bypass by setting AllowUpgradesWithUnsupportedTPMOrCPU to 1.
  • Enables Upgrade Assistant to proceed by setting UpgradeEligibility to 1 under the current user.

Registry Keys Modified or Removed
