Microsoft confirms TPM 2.0 is a hard floor for Windows 11

Microsoft has published a blog post, trying to dispel some of the confusion around Windows 11's system requirements. First and foremost, the company makes it clear that TPM 2.0 and 8th generation Intel and 2nd generation Ryzen are hard floors. Microsoft adds that based on the feedback during Windows 11's testing process, support for 7th generation Intel and 1st generation Ryzen processors might be added.

Using the principles above, we are confident that devices running on Intel 8th generation processors and AMD Zen 2 as well as Qualcomm 7 and 8 Series will meet our principles around security and reliability and minimum system requirements for Windows 11. As we release to Windows Insiders and partner with our OEMs, we will test to identify devices running on Intel 7th generation and AMD Zen 1 that may meet our principles.

There are ways around these hard floors, through registry hacks and custom Windows 11 ISOs, but updates might break those, and who knows if Microsoft will plug those holes.
