Windows 11, the truth and nothing but the truth: It's amazing the chatter about Win 11 going on and "are you using it" or "will I be able to upgrade to it", and on and on and on. First, as you probably know, Microsoft initially came out with a severely flawed "PC Health Check" tool to determine if your PC could support Win 11. It should have been named The Terminator because 99% of the machines that ran it would fail. MS has recently come out with a "revamped" tool (you have to be a member of the Insider Program to download it). But let me get to the crux of the whole issue with whether or not you can run Win 11 on your current Windows 10 machine. There were two ways to run Win 11, one way is If you have a PC that completely supports the requirements for Win 11 and the other is to install Win 11 using an ISO from Microsoft's Insider Program (there's also a few 3rd-party sites offing ISO downloads for Win 11 as well). The latter method is how most users running Win 10 have been able to run Win 11 on hardware that does NOT strictly comply with all of the Win 11 stated requirements. The initial ISOs from Microsoft have "relaxed" hardware (and software) requirements for installing Win 11 and are designed to access Win 11 on hardware that does not actually fully support Win 11. So you can install the Win 11 ISO on a machine that does not fully meet the Win 11 requirements. Microsoft is aware that many Win 10 users have installed the Win 11 ISO and think they can stay with it going forward on hardware that is "non-compliant". However - and this is a big however - Microsoft has recently stated that anyone running Win 11 ISO's from the Insider Program will be bumped back down to Win 10 (by way of Win 11 updates) if their machines are not compliant. So Microsoft has closed this back-door into installing Win 11 on machines that are not compliant. But, the straw that breaks the camel's back with non-compliant hardware is not so much whether your machine has TPM 2.0 (many do), or whether your mother board has a UEFI bios (many do) or whether it supports Secure Boot (many do) but whether the processor is on Microsoft's list of "approved" processors. So to put this another way, you can't run the retail release of Win 11 on a machine that does not have a processor on Microsoft's approved processor list. So far, MS has allowed some 2nd gen AMD Ryzen, selected 7th gen Intel, and mainly 8th gen Intel processors. In short, even if your PC meets 99% of the Win 11 requirements, if the processor is not one that is on the approved list of processors, your are for all intents and purposes, screwed. And again, even if you're running Win 11 now on non-compliant hardware, you will eventually be bumped back down to Win 10 by MS.
