The latest Windows 11 install script bypasses TPM

As we near the official release of Windows 11, there appears to be a new script that allows users to install the new OS on devices that do not meet the minimum requirements.

Microsoft has been releasing system requirements for devices that are compatible with Windows 11.

New gateway

Part of the OS system requirements includes TPM 2.0, newer CPUs, and many more. The new script works on virtual machines and allows them to upgrade to the latest Windows Insider build.

The script comes in a batch file released as part of the Universal MediacreationTool wrapper allowing users to create an ISO for any Windows version.

The main script is the MediacreationTool.bat that creates the ISOs and the Skip_TPM_Check_on_Dynamic_Update.cmd that configures your device and bypasses all mandatory hardware checks set for Windows 11.

When executed on a device, some of the tasks performed include:

• Creates a ‘AllowUpgradesWithUnsupportedTPMOrCPU‘ value.
• Registers a WMI event subscription named ‘Skip TPM Check on Dynamic Update.’ 
• Deletes the ‘C:\$WINDOWS.~BT\appraiserres.dll‘ file during the launch of vdsldr.exe in Windows 11 setup.

For those who like to play but want to use older systems, this may help:https://t.co/Sozzz5hC9B
As noted, Microsoft COULD do things that would prevent critical updates and (though I think less likely) it could affect system stability when running on unsupported hardware.

Risks ahead

Whereas this may seem like an easy method for users whose devices failed to meet system requirements and had to purchase new devices, they should be careful with this script as it exposes them to performance issues and an array of bugs. In addition, you risk missing critical security updates making your connection less secure.

Microsoft maintains its strong stance on devices meeting system requirements to install Windows 11.

If you must install this script, only do so on test devices.
