I was running an insider's build of Win11 on my home desktop for quite a while just fine, until they seemed to have actually made the TPM a hard requirement, and I rolled back to Win10. It's a shame because it's an 8 year old beefy PC that otherwise runs perfectly fine and I didn't have any issues with Win11 otherwise on it.
