New Windows 11 installation script bypasses TPM, system requirements



A new script allows you to install Windows 11 on devices with incompatible hardware, such as: B. missing TPM 2.0, incompatible CPUs or missing Secure Boot. Even better, the script works on virtual machines too, so you can upgrade to the latest Windows Insider build.

When Windows 11 was first announced, Microsoft released the new system requirements for the operating system, which included a TPM 2.0 security processor, secure boot, newer CPUs, and at least 64 GB of hard drive space.

When Microsoft realized that a lot of people, especially in business, would test Windows 11 preview builds on virtual machines, they did have excluded them from the system requirements.

However, Microsoft now requires compatible hardware on virtual machines and takes a clear stance on its system requirements and even goes so far that people who install Windows 11 on incompatible hardware may not receive security updates.

For those willing to run Windows 11 on incompatible hardware, a script has been released that allows new installations and upgrades to bypass the system requirements of the operating system.

Script bypasses the system requirements of Windows 11

This new script was released as part of the extremely useful Universal MediaCreationTool wrapper, a batch file that allows you to create an ISO for any version of Windows 10, with support for Windows 11 added last week.

While the main script of it Open source project is the ‘MediaCreationTool.bat‘used to create Windows ISOs, it also contains a script called’Skip_TPM_Check_on_Dynamic_Update.cmd‘,’ which configures the device to bypass compatible hardware tests.

When run on a Windows 10 or Windows 11 device, the Skip_TPM_Check_on_Dynamic_Update.cmd script performs a variety of tasks, including:

  • Create the ‘AllowUpgradesWithUnsupportedTPMOrCPU‘Value below the HKEY_LOCAL_MACHINE SYSTEM Setup MoSetup Registry key and put it on 1.
  • Registers a WMI event subscription called ‘Skip TPM Check on Dynamic Update’ that uses the ‘C: $ WINDOWS. ~ BT appraiserres.dll‘File if the vdsldr.exe The executable file is started during the setup of Windows 11.

    Note that the created WMI event subscription will remain in effect until you run the Skip_TPM_Check_on_Dynamic_Update.cmd script again, which will delete the event subscriptions. You can do this after you’ve installed or updated Windows 11.

Before using this script, when trying to upgrade a Windows 11 Build 22449 virtual machine to the latest preview build, the upgrade failed because setup could not see the safe boot function, a TPM 2.0 processor, and the system hard drive was too small was.

However, after running this script, we were able to easily install the latest Windows 11 preview version 22463.

Anyone who chooses this workaround should be aware that it is an unsupported method of installing Windows 11 and it can lead to performance issues or other errors while using the operating system. Additionally, Microsoft may not provide security updates for unsupported devices, making your installation likely to be less secure.

Therefore, you should only use this method in test environments and not on production devices.
