Ok here's my 2 cents. LOL
They said that TPM has been around for the last 5 - 7 years.
“Almost every CPU in the last 5-7 years has a TPM,” explains David Weston, director of enterprise and OS security at Microsoft.
If that's the case, then those CPU's should be supported to be able to upgrade to Windows 11.
My PC, which is 3 yrs old, has TPM2.0 And passes every requirement except the CPU.
