My machine is X220 which is not compatible to upgrade to Windows 11, since I cannot leave the Insider Dev Channel without reinstall the machine without data loss….So, I decided to force my machine to upgrade to Windows 11 GA to keep my data and also installed program.
Since my machine did not have TPM, I need to upgrade Windows 11 without TPM
- Go to "HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup" and press Enter. Add a DWORD value, name it "AllowUpgradesWithUnsupportedTPMOrCPU," and set it to 1.
- Go to HKEY_LOCAL_MACHINE > SYSTEM > Setup and create the key LabConfig.
Add a DOWRD value called "BypassTPMCheck" and set it to 1. Then add another one called "BypassCPUCheck" and set that to 1 as well.
Then create a ISO with the Media Creation Tool, extract all file into a folder.
Then delete the appraiserres.dll and also mount a Windows 10 ISO to copy the aappraiserres.dll into the Windows 11 installation source folder
launch setup, and perform an in-place upgrade on your system.
After the upgrade completed, you will receive a message you cannot enter the Windows insider program on this machine for Windows 11.
And my machine running on the Windows 11
