Interesting. If I understand correctly, the "bypass" is https://github.com/coofcookie/Windows11Upgrade/blob/1.0.0/Wi... which is a copy of https://github.com/AveYo/MediaCreationTool.bat/blob/main/MCT... which appears to be intentionally cryptic.

It sets HKLM\SYSTEM\Setup\MoSetup\AllowUpgradesWithUnsupportedTPMOrCPU=1 which is mentioned by Microsoft in https://support.microsoft.com/windows/ways-to-install-window... which seems reasonable.

According to the comment, the rest of the script "uses IFEO to attach to Virtual Disk Service Loader process running during setup, then erases appraiserres.dll [...] it must also do some ping-pong renaming of vdsldr in system32\11" Could anyone explain this in more detail?

Also note, according to https://github.com/AveYo/MediaCreationTool.bat/issues/11 it skips the CPU and TPM checks, but not the Secure Boot checks.
