If you have a device that does not have TPM available then you are not able to install Windows 11, which usually means you have to buy a new device that does support TPM, but this may not be ideal for many people.
What if you want Windows 11 without TPM support?
Well, it used to be in Windows 11 versions (previous to 22H2) that you could set the registry key and continue with the setup:
REG ADD HKLM\SYSTEM\Setup\MoSetup /v AllowUpgradesWithUnsupportedTPMOrCPU /t REG_DWORD /d 1 /f
Then setup would continue on without the TPM support however after you set this key this no longer works as you get the TPM failing (as all the other requirements are valid)
This means if you have Window 11 (later than 22H2) then you need to amend where these registry keys are added, as Microsoft tried to get crafty by moving these keys, however the new location for TPM is :
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassTPMCheck /t REG_DWORD /d 1 /f
If you have an issue with the Secure Boot or RAM check you can bypass that as well with the relevant key below:
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassSecureBootCheck /t REG_DWORD /d 1 /f
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassRAMCheck /t REG_DWORD /d 1 /f
When these keys have been successfully installed you will now be able to continue on with the setup process:
If you choose to take this method then remember the following facts are then true for now of the future:
- This method bypasses important security features
- Your system may be more vulnerable to certain attacks
- You won't receive guaranteed Windows Updates
- Microsoft may block updates or features in the future
- Performance and stability issues may occur
- No official support from Microsoft
