This script was created to modify the Windows installation environment dynamically, removing these blocks so that the setup process can proceed on older hardware.
Additionally, the script uses a /Product Server trick to disable the stricter checks performed by the Dynamic Update (WU) component of the setup, ensuring that the installation does not get stuck later on. Risks and Considerations (As of 2026) skip-tpm-check-on-dynamic-update.cmd
The script leverages a Windows feature called to intercept key setup processes. When executed, it creates an IFEO entry for SetupHost.exe (located in the $WINDOWS.~BT\Sources directory). This configuration ensures that when the Windows setup routine launches, the script can intervene and modify its behavior in real-time. This advanced technique allows the script to apply different parameters depending on the installation method—whether it is an ISO-based install or a dynamic Windows Update—providing robust and adaptive compatibility checking.
If you are using skip-tpm-check-on-dynamic-update.cmd today, plan to upgrade your hardware within the next 2-3 years. The cat-and-mouse game between Microsoft and bypass scripts cannot continue indefinitely when security is the stated priority.
skip-tpm-check-on-dynamic-update.cmd was born to solve this specific problem. It intervenes between the local setup and the Microsoft server, preventing the dynamic update from overwriting your bypass settings. Unzip the folder to your desktop or a
If you prefer not to use a script, you can manually allow upgrades on unsupported hardware by editing the registry: Press Win + R , type regedit , and press Enter. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup . Right-click, select . Name it: AllowUpgradesWithUnsupportedTPMOrCPU . Double-click the new value and set it to 1 .

With the script active, you can go to Settings > Update & Security and run the Windows 11 upgrade if offered. Using ISO: Mount your Windows 11 ISO and run setup.exe . Behind the Scenes: How the Bypass Works
The skip-tpm-check-on-dynamic-update.cmd script intercepts this specific check, tricking the installer into thinking your hardware meets all criteria, allowing the upgrade or feature update to proceed seamlessly.

Microsoft is currently developing "Windows 12" (codenamed Hudson Valley). Leaks suggest the TPM requirement will become stricter , not looser. Pluton security processors (Microsoft's version of TPM built into the CPU) may become mandatory. Dynamic Update bypass scripts will likely become less effective over time as Microsoft moves compatibility checks deeper into the UEFI firmware.
This can happen for a few reasons:
