Skip-tpm-check-on-dynamic-update.cmd May 2026
The script bypasses the check during the current installation. The next major feature update (24H2, 25H1, etc.) will re-run compatibility checks. You must run the script again, or the update will fail.
Hyper-V, VMware, and VirtualBox users often want to test Windows 11 without enabling passthrough TPM (which requires Generation 2 VMs and extra configuration). The script allows a clean, software-only TPM bypass.

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
The script skip-tpm-check-on-dynamic-update.cmd is a well-known utility, primarily developed by AveYo 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.
Below is a draft of the content typically found in this script, organized by its functional components. Core Script Logic (.cmd Content) skip-tpm-check-on-dynamic-update.cmd
The script works by using Image File Execution Options (IFEO) to "hijack" the SetupHost.exe process. Instead of running the installer directly, Windows runs this script first, which then clears the hardware checks before launching the actual installer.
The skip-tpm-check-on-dynamic-update.cmd is an open-source script by AveYo, primarily used to bypass hardware requirements (TPM 2.0, Secure Boot, and CPU) when upgrading to Windows 11. It is part of the Universal MediaCreationTool wrapper project. Key Functionality
The script automates several complex workarounds to trick the Windows installer into ignoring hardware blocks:
Registry Modification: It sets AllowUpgradesWithUnsupportedTPMOrCPU to 1 in the Windows registry.
WMI Event Subscription: It registers an event that automatically deletes the appraiserres.dll file during the setup process, which is the file responsible for checking hardware compatibility.
Dynamic Updates: It allows users to perform "In-place upgrades" directly through Windows Update or by running setup.exe from a mounted ISO without being blocked by the "This PC can't run Windows 11" error. User Experience & Reliability
Ease of Use: The script is designed as a "toggle." Running it once installs the bypass; running it a second time removes it. The script bypasses the check during the current
Version Compatibility: Users have successfully used it to upgrade through multiple versions, including the recent 24H2 release. However, some users have reported issues with specific builds (like 25905) due to permission errors or path changes.
Installation Method: It is often used by copying the "Raw" code from GitHub, saving it as a .cmd file, and running it as an Administrator. Critical Risks & Limitations Enable TPM 2.0 on your PC - Microsoft Support

. 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 If this script doesn’t work for your scenario, consider:
: 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
The file skip-tpm-check-on-dynamic-update.cmd appears to be a script designed to modify or bypass certain checks related to Trusted Platform Module (TPM) during a dynamic update process, likely in a Windows environment. TPM is a hardware component that provides a secure environment for cryptographic operations and is used in various security features, including Windows BitLocker and Windows Hello.
The feature for such a script could include:
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.
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.
