everyone without a TPM 2.0 add-on card, or those with processors older than 7th Gen Intel Core 'Kaby Lake,' or AMD Ryzen 2000 'Pinnacle Ridge' series. While these requirements do make some sense going forward, this walls off a lot of potential users, i.e.
Besides the much-talked about TPM 2.0 spec compatible hardware Trusted Platform Module as a system requirement, there's also new requirements for UEFI Boot, and installation on a GPT partitioned drive (no more MBR boot for Windows 11). What do you do? With Windows 11, Microsoft introduced new requirements for compatible hardware, and these are purely software-only checks-nothing really requires it. So you have a $2,000 Core i7-6950X HEDT processor, which you thought would last forever, but Windows 11 Setup stands in your way with its steep system requirements that include TPM and Secure Boot.
