TPM 2.0 requirement and install Windows 11


Well-Known Member
Some of you, like myself, may have a laptop or desktop that has a few years on it and does not have the TPM 2.0 (Trusted Platform Module) it may have only 1.0 or 1.1 - Windows 11 requires 2.0 and above so this means you will not be able to install Windows 11 do to this requirement, but no worries there is a way around this - While this is not an option that will be available to the average user, it is possible to edit the registry to make it possible to install Windows 11 on a computer that does not have TPM 2.0. Mostly for computers made prior to 2017
Use the following steps to install Windows 11 on an "incompatible" system:
  1. Start the installation of Windows 11, wait for a "This PC can't run Windows 11" message to appear and then pressing Shift + F10
  2. At the command prompt, type regedit and press Enter
  3. Navigate to HKEY_LOCAL_MACHINE \ SYSTEM \ Setup and create a new key called LabConfig
  4. Under this key, create a new DWORD (32-bit) value called BypassTPMCheck and set its value to 1
  5. Create another new DWORD (32-bit) value called BypassRAMCheck and set its value to 1
  6. Create a third new DWORD (32-bit) value called BypassSecureBootCheck and set its value to 1
  7. Close the Registry Editor, type exit and hit Enter
  8. When you are returned to the Windows Setup screen, click the back arrow and then restart the installation process.
  9. You should find that you are able to install Windows 11
This only works on "Clean Installs" not an upgrade
