The script monitors the Windows Setup process tree. When it detects that setup.exe has launched the Dynamic Update downloader (wuauclt or setup child processes), it temporarily suspends them or replaces key DLLs before they load into memory.
skip-tpm-check-on-dynamic-update.cmd is not for the average user. It is a surgical tool for enthusiasts, IT pros, and developers who understand the trade-off between security compliance and hardware utility.
When to use it: You have a TPM 1.2 or an Intel 7th Gen / AMD Ryzen 1000 series CPU, you need an in-place upgrade without data loss, and you accept that Microsoft may revoke update privileges later.
When to avoid it: You are a business handling sensitive data (compliance mandates TPM 2.0), you rely on BitLocker, or you are uncomfortable with command-line tools.
Ultimately, the script exemplifies the tension between vendor control and user freedom. Microsoft is right that TPM 2.0 improves security. But users are also right that perfectly functional hardware shouldn't become e-waste overnight. With careful use of skip-tpm-check-on-dynamic-update.cmd, you can bridge that gap—one batch command at a time.

Skip_TPM_Check_on_Dynamic_Update.cmd script is a highly regarded community utility designed to bypass Windows 11 system requirements—specifically TPM 2.0, Secure Boot, and RAM checks—during in-place upgrades and Windows Updates. Created by developer as part of the MediaCreationTool.bat
project, it is widely considered one of the most reliable methods for installing Windows 11 on unsupported hardware. Core Functionality
While Windows 11 offers a sleek interface and modern features, its strict system requirements—notably TPM 2.0—have left many users with capable but "unsupported" hardware behind. The skip-tpm-check-on-dynamic-update.cmd script is one of the most reliable community-developed tools to bridge this gap, allowing for seamless upgrades even when your PC doesn't meet Microsoft's official criteria. What is skip-tpm-check-on-dynamic-update.cmd?
Developed by the developer AveYo as part of the Universal MediaCreationTool wrapper, this batch script is designed to bypass hardware compatibility checks during a Windows 11 upgrade. Unlike manual registry edits that only work for clean installs, this script specifically targets Dynamic Updates, which are the checks Windows performs right before it starts an in-place upgrade. How the Script Works
The script uses a combination of registry modifications and system monitoring to "trick" the Windows installer:
Registry Modification: It adds the AllowUpgradesWithUnsupportedTPMOrCPU value to the Windows Registry, which is a known (though often insufficient on its own) bypass method.
WMI Event Subscription: This is the "secret sauce." The script registers a Windows Management Instrumentation (WMI) event that watches for the vdsldr.exe process (Virtual Disk Service Loader) during the setup process.
File Deletion: When it detects that process, it automatically deletes a file called appraiserres.dll from the temporary installation folder. This file is responsible for performing the hardware compatibility check; without it, the installer simply proceeds as if the check passed.
The "/Product Server" Trick: Later versions of the script often use a parameter that tells the installer to run in "Server" mode, which traditionally has fewer hardware restrictions, though it still installs the standard consumer version of Windows. Step-by-Step Guide to Using the Script
If you're ready to upgrade an unsupported PC, follow these steps to use the AveYo MediaCreationTool wrapper or the standalone script: skip-tpm-check-on-dynamic-update.cmd
Download the Tool: Navigate to the official GitHub repository and download the project as a ZIP file.
Extract the Files: Unzip the folder to your desktop or a location of your choice.
Locate the Script: Inside the extracted folder, look for a subfolder named bypass11. Inside, you will find Skip_TPM_Check_on_Dynamic_Update.cmd.
Run as Administrator: Right-click the .cmd file and select Run as administrator. A command prompt window will briefly appear, confirming that the bypass is installed.
Start Your Upgrade: You can now run the official Windows 11 Installation Assistant or use a standard Windows 11 ISO to begin the upgrade process. The "This PC doesn't meet requirements" error should no longer appear. Important Considerations and Risks
While the script is highly effective, users should be aware of several factors before proceeding:

The script skip-tpm-check-on-dynamic-update.cmd is a well-known open-source tool by developer , typically found in the MediaCreationTool.bat repository on GitHub
. It is designed to bypass Windows 11 hardware requirements—specifically the TPM 2.0, Secure Boot, and CPU checks—allowing users to upgrade unsupported PCs via Windows Update or a mounted ISO. What the Script Does Registry Modification : It sets the AllowUpgradesWithUnsupportedTPMOrCPU in the Windows Registry under HKLM\SYSTEM\Setup\MoSetup Dynamic Bypass
: It registers a WMI event subscription or an Image File Execution Options (IFEO) debugger that automatically deletes or patches compatibility check files (like appraiserres.dll hwreqchk.dll ) during the "dynamic update" phase of Windows Setup. Toggle Functionality
: Running the script once installs the bypass; running it a second time removes it. How to Use It : Obtain the script from the official GitHub source or copy the raw code into a new Run as Administrator : Right-click the file and select Run as administrator Confirm Installation
: A command prompt window will open and confirm the bypass is "INSTALLED". Start Upgrade Via Windows Update The script monitors the Windows Setup process tree
: Go to Settings > Update & Security and check for updates to trigger the Windows 11 download. : Mount a Windows 11 ISO and run
: When the installer starts, it may display "Windows Server" as a cosmetic label; this is a side effect of the bypass method, but it will install the correct standard version (Home/Pro). Key Considerations
Skip_TPM_Check_on_Dynamic_Update.cmd is an open-source batch script designed to bypass Microsoft's strict hardware requirements—specifically the TPM 2.0 and supported CPU checks—when installing or upgrading to Windows 11 on older machines. Developed by AveYo as part of the Universal MediaCreationTool (MCT) wrapper, it allows users to perform "in-place" upgrades through Windows Update or a mounted ISO that would otherwise be blocked. How it Works
The script uses two primary technical mechanisms to trick the Windows installer:
Registry Modification: It creates a DWORD value named AllowUpgradesWithUnsupportedTPMOrCPU set to 1 under HKLM\SYSTEM\Setup\MoSetup, which is a known official-yet-hidden registry bypass documented by Microsoft.
WMI Event Subscription: It registers a background task that automatically deletes appraiserres.dll from the temporary installation folder (C:\$WINDOWS.~BT) whenever the setup begins. This DLL is the component responsible for performing the hardware compatibility check. Key Features
Toggle Functionality: Running the script once installs the bypass; running it a second time removes it, making it easy to use only when needed for feature updates.
Universal Compatibility: It is frequently updated to work with newer Windows 11 versions, including 24H2, though users sometimes report it works best when choosing the "Not right now" option for downloading setup updates during the installation process.
Automation: Because it targets "Dynamic Updates," it aims to allow Windows Update to handle the transition automatically, rather than requiring a clean install from a USB. Usage & Availability
You can find the raw code for the script on its official GitHub repository or as part of the larger MediaCreationTool.bat project. Guides from Tom's Hardware and PCrisk suggest saving the raw text as a .cmd file and running it as an administrator to apply the patch.
Note of Caution: Bypassing these requirements may leave your system without some security features like BitLocker and could potentially lead to stability issues or a lack of official support from Microsoft in the future.
Using the skip-tpm-check-on-dynamic-update.cmd script is relatively straightforward:
No bypass script is without consequence. Here are the critical risks.
Unlike simple registry hacks that only work after Windows is installed, this script targets the setup process itself. While the exact code varies by version (users constantly update these scripts as Microsoft patches loopholes), the core methodology involves:
The infamous appraiserres.dll file contains the logic for: Disclaimer: This article is for educational purposes
The script replaces the dynamically downloaded version of appraiserres.dll with a modified or empty version that returns "compatible" for all checks. Because the batch file acts during the update, the new file is swapped before the setup engine executes the hardware scan.
