runs. When triggered, the script strips away the parameters that check for TPM and Secure Boot, allowing the installation to proceed on unsupported hardware. The Script Code You can create this file by copying the code below into and saving it as skip-tpm-check-on-dynamic-update.cmd

The strict hardware requirements for Windows 11 often block perfectly capable machines from upgrading. Microsoft restricts installations on systems without Trusted Platform Module (TPM) 2.0, Secure Boot, or an officially supported processor.

: Go to Settings > Update & Security and check for updates to trigger the Windows 11 download. : Mount a Windows 11 ISO and run

With the script active in the background, you can now initiate your upgrade using your preferred method: skip-tpm-check-on-dynamic-update.cmd

Click on the file, select , right-click the page, and choose Save as... to download it as a .cmd file. Step 2: Run as Administrator Close all active Windows Update windows.

: The script registers a Windows Management Instrumentation (WMI) event called "Skip TPM Check on Dynamic Update." This event triggers when vdsldr.exe (the Virtual Disk Service Loader) starts during Windows 11 setup, automatically deleting the appraiserres.dll file that contains the hardware check logic.

TPM, or , is a specialized hardware chip designed to provide security-related functions at the hardware level. Its primary roles include secure cryptographic key storage, device authentication, and platform integrity verification. TPM works in conjunction with features like Secure Boot to ensure that only trusted software loads during the system startup process, protecting against rootkits and other low-level malware. to download it as a

: If the automated Windows Update utility reverts your bypass, use the ISO method outlined in Step 3 to force the upgrade offline.

Using this script bypasses official security recommendations. Systems running Windows 11 on unsupported hardware may not receive all security updates and could experience stability issues. Always back up your data before attempting a bypass upgrade. AI responses may include mistakes. Learn more

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. It specifically targets the appraiserres.dll file

At its core, skip-tpm-check-on-dynamic-update.cmd is a batch ( .cmd ) script designed to automate the bypass of Microsoft's compatibility checks during the Dynamic Update phase of a Windows 11 feature upgrade.

It specifically targets the appraiserres.dll file, which is responsible for evaluating system compatibility during installation.
