How to install Windows 11 without TPM [Bypass CPU requirements]

Windows 11 is a 64-bit OS only. Like macOS, Microsoft has also moved to support only 64-bit systems with their latest operating system. In addition to the 64-bit requirement, Windows 11 also requires a secure boot of UEFI and TPM 2.0 on a system to run them. For many users, it is the TPM chip version that prevents them from upgrading to Windows 11.

The TPM chip is a hardware component. If your system does not have one, it is likely that you will need to purchase a new system. This chip is not just something you can upgrade as RAM. Your motherboard may not support a newer version of the chip. That said, you can bypass the Windows 11 requirement for the chip.

To do this, it is best to upgrade to Windows 11 from Windows 10. Before upgrading, you need to edit the registry and tell Windows 10 to avoid the TPM requirement.

This is generally safe but we strongly encourage you to restore important files on your system before proceeding. If possible, create a restore point. This will work for systems with both supported and unsupported CPUs.

Clean install Windows 11

If you are not upgrading to Windows 11 from Windows 10, and instead choose to clean the new OS, you still need to edit the registry. The trick is to get to the table before installing Windows 11.

  1. Shut down your computer.
  2. Turn the system on and go to BIOS.
  3. Switch the first boot device to USB.
  4. Connect the USB disk / Windows 11 installation.
  5. Restart the computer.
  6. When the Windows 11 installation prompts, you will see a message “This PC cannot run Windows 11”.
  7. Press the Shift + F10 keyboard shortcut to open Command Prompt.
  8. In Command Prompt, enter regedit and tap Enter.
  9. The editor of the registry will open.
  10. Follow the steps in the previous section and make all edits to registration.
  11. Once the edits are complete, enter Revolution in the Command Prompt window.
  12. Click the Back button on “This PC cannot run the Windows 11 screen”.
  13. Run the installation again and it should work.


Microsoft does not routinely create software that prompts users to purchase new hardware. If you have a system that is too old to have a TPM 2.0 chip, you should consider purchasing a new system. The TPM chip adds better security to your system and going forward, you will need it. It is also possible that Microsoft will capture this work around leaving you in a bind.
