The is an open-source script by AveYo , primarily used to bypass hardware requirements (TPM 2.0, Secure Boot, and CPU) when upgrading to Windows 11. It is part of the Universal MediaCreationTool wrapper project. Key Functionality
It is considered one of the most reliable methods, particularly for in-place upgrades through Windows Update.

During this Dynamic Update phase, the setup downloads a fresh copy of the compatibility checker ( appraiserres.dll ). That checker rigorously enforces TPM 2.0 and CPU whitelists. Traditional bypasses (like modifying sources/ files on an ISO) fail because Dynamic Update overwrites them mid-installation.
The script works by using to "hijack" the SetupHost.exe process. Instead of running the installer directly, Windows runs this script first, which then clears the hardware checks before launching the actual installer.
