I installed Windows 11 with an unsupported CPU, kinda funny how it just worked despite all their screeching that it wouldn't work and updating not working, but installing with installation media was flawless.
It's a real bitch, automatically logging me into my partner's account for the whole system and overriding my local user settings when I open MS Office apps Excel or Word (but that's just Windows), and it cries about my lack of TPM on those apps and the Start menu when it does log in and cries about me not being logged into a MS account otherwise, but you know what? Everything still actually operates.
An OS is a tool.
And you are a tool if you use the wrong tool for a purpose.
E.g. an essential program that only runs on windows and is either impossible or troublesome to run elsewhere.
I agree. That's why I wouldn't install Windows 11 on an unsupported CPU in the first place, let alone keep it installed after having one issue after another like the comment I replied to had mentioned.
