Since we mounted the file directly from the Win11_OS folder, it will be saved back to where it needs to go. What we are actually doing is committing the registry changes that we made, including the BypassTPMCheck DWORD into the registry and saving that to the boot.wim file. Commit the changes to the boot.wim fileĪt this point, we can commit the changes to the boot.wim file. Now, we need to unload the registry hive before we commit the changes to the boot.wim file. However, there are some prerequisites we need to have installed: There are only a few things we need to do to bypass the TPM check in the Windows 11 ISO. So, I wanted to create a customized ISO that bypasses this check so I don’t have to do this manually each time I install Windows 11 from an ISO as well as with Packer builds. Several of my lab hosts do not have TPM chips. However, I wanted to use the GA release of Windows 11 in my home lab and with automation tooling. Create Windows 11 ISO with No TPM Checkįirst of all, why do I want to do this? This is obviously not supported by Microsoft.

Let’s take a look at how to create a Windows 11 ISO with no TPM check and see how to do this. However, what if we could modify the ISO itself to get around the TPM check and set the “flag” to “off” for the TPM check with the GA release? This would mimic the behavior we have seen with the Preview builds? Is this possible? Yes.

I have posted a couple of posts that have resonated with many, including the following: However, Microsoft has now flagged this check on with the GA release of Windows 11. The Preview Builds did not check for a proper TPM. Many have had issues with the TPM check since the release of Windows 11 GA.

The last few days have been spent with a lot of Windows 11 time.
