Major annual feature updates (e.g., 23H2 to 24H2) will re-introduce hardware checks. You will need to run this script again for every major yearly version upgrade. However, standard monthly security patches usually download and install without issue.

Systems with very old CPUs may experience minor driver fragmentation or performance drops. Troubleshooting Common Errors

It typically utilizes a /Product Server trick, which tricks the setup process into treating the installation as a server upgrade, which has less strict security requirements, thus bypassing the restrictions.

While other bypass methods involve modifying the installation media directly, this script adopts a different and more elegant approach. Its key differentiators include:

Before proceeding, backup all critical data. While this script is highly reliable, forcing upgrades on unsupported hardware carries inherent risks. Step 1: Download the Script

The script also automatically integrates with the Windows installation process at several key points, providing flexibility for different scenarios. Major annual feature updates (e

The during in-place upgrades and feature updates. Created by open-source developer AveYo as part of the popular Universal MediaCreationTool wrappers , this lightweight script manipulates how Windows Setup processes hardware validation. It allows users to run Windows 11 on older PCs lacking a Trusted Platform Module (TPM 2.0) , Secure Boot , or a supported CPU . What is skip-tpm-check-on-dynamic-update.cmd ?

: Bypassing requirements can lead to system instability or lack of future security updates. Official Documentation

Earlier versions of the script also made use of a WMI (Windows Management Instrumentation) event subscription. This method created a named subscription called "Skip TPM Check on Dynamic Update", which was designed to automatically delete a critical compatibility-check file ( C:\$WINDOWS.~BT\appraiserres.dll ) during the Windows 11 setup process. It is important to note that this approach has been refined in later versions, and the script now uses more reliable methods, but the core principle of intercepting and disabling the checks remains the same. Systems with very old CPUs may experience minor

During an upgrade, Windows creates a temporary folder called C:\$WINDOWS.~BT . Inside this folder is a critical file, appraiserres.dll , which is responsible for performing the hardware compatibility check. The script registers a special WMI (Windows Management Instrumentation) event that automatically deletes this appraiserres.dll file at the exact moment the installer tries to use it. With this file missing, the checks cannot be performed, and the installation continues unimpeded.

The script skip-tpm-check-on-dynamic-update.cmd is a well-known utility, primarily developed by as part of the Universal MediaCreationTool wrapper on GitHub . It is designed to bypass Windows 11 hardware requirements (TPM 2.0, Secure Boot, and CPU) during a "Dynamic Update"—which includes in-place upgrades via Windows Update or using setup.exe from a mounted ISO.
