Bypass Windows 11 Upgrade Assistant / PC Health Check / TPM and CPU Settings

To bypass the Windows 11 Upgrade Assistant and avoid the TPM and CPU requirement checks, you can modify specific registry values to trick the system into thinking your computer meets the necessary requirements. This method addresses common error messages, 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.

The Upgrade Assistant checks the following registry key to determine eligibility:

• HKEY_CURRENT_USER\Software\Microsoft\PCHC
  • Set the UpgradeEligibility value (DWORD) to 1.

This alone will allow the Upgrade Assistant to proceed, but to complete the upgrade process on systems with unsupported TPM or CPU, you must also modify this registry key:

• HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
  • Set the AllowUpgradesWithUnsupportedTPMOrCPU value (DWORD) to 1.

Once both values are configured, you can upgrade to Windows 11 by running the 4 MB Upgrade Assistant file rather than using the full Windows 11 ISO. This method allows you to bypass hardware compatibility checks while minimizing the hassle of downloading the entire ISO file.

How to Use

Simply save the reg file and run it then hit Yes to apply the tweaks to the system. No scripts or excessive modifications required.

Windows11-Enable-Upgrade.reg

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\PCHC]
"UpgradeEligibility"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup]
"AllowUpgradesWithUnsupportedTPMOrCPU"=dword:00000001

I have read that the Win 11 upgrade assistant doesn't remove your apps or data ( dont know how true that is ), I tried those bat files and reg files and it still says I need secure boot, so I edited the reg files needed added a few in to bypass those issues and it still comes up I need secure boot.

Win 11 upgrade assistant doesn't remove your apps or data:

It's pretty true actually.

I did it on a domain joined system remotely lol. Nothing at all lost, not even remote access.

I don't think it's related to the version of Win 10 tbh.

It's possible your system is booting in an older way (non-UEFI) - not really sure.

I'd take a complete backup (either way) and wipe it 😎

Yer I tired the upgrade assistant and kept getting I need secure boot even thou I disabled those steps, I can boot both ways UEFI and non UEFI
anyway I put it down to it can't be done on these machines so I'm going to give PCTrans ago, just putting the image onto the 2nd machine now so I can try it.

Secure boot needs UEFI, but you shouldn't be able to boot either way (UEFI or BIOS), only one way. If you can boot either way, Windows may have some boot remnants from a prior OS which may be part of the problem.

it's probably best to make a full backup then wipe it (remove partitions) and do a clean install. Then reinstall programs and pull in the files you need.

I managed to get it all going but I had to use Rufus

To bypass Windows 11 Upgrade Assistant checks, modify two registry values: set UpgradeEligibility to 1 in HKEY_CURRENT_USER\Software\Microsoft\PCHC, and AllowUpgradesWithUnsupportedTPMOrCPU to 1 in HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. After running the registry file, you can upgrade without hardware checks using the Upgrade Assistant.

Thanks @PhoebeBaxter , worked with your suggestion. I was able to upgrade using Windows 11 Installation Assistant.
