those of you who have at least a 5 year or newer system look in your motherboard manual https://forums.mydigitallife.net/th...odename-sun-valley.83555/page-61#post-1668229
PSA: Microsoft has started downright locking unsupported computers out of the beta and dev insider channels. I've seen tree screenshots of other people with older PCs (Legacy BIOS, much older CPUs...) The Dev and Beta channel options are now gone from the Insider settings page. With only "Release Preview" available. Edit: This has now been confirmed to me by a Reddit user.
For Ryzen owners, look for AMD fTPM Configuration. If it's set to discrete and you don't have a discrete TPM, no TPM will be presented to Windows and you'll get the unsupported error during 21996 setup. If it's set to enabled, it will enable a TPM from the CPU. That setting is seemingly named the same across various vendors and chipsets. For Intel, this is handled by the Management Engine (IME), presumably with newer chipsets (Skylake+?) having TPM 2.0 support. If you've used me_cleaner, you'll likely not be able to use that firmware TPM.
Feels like Vista days happening all over again. Don't get me wrong, I like Windows 11, in fact I'm using it right now... and very happy my custom built desktop is compatible and ready for the final release in october... But if Microsoft keeps these restrictive system requirements... Man... it will probably fail hard... very hard.
Was this somehow not expected? It would make zero sense for them to push an update to someone's computer that they couldn't even run. I still suspect they will relax the requirements when they realize how few people are willing to buy a new computer for this os.
