In my case the Intel Core i7 processor family is not supported for windows 11. Granted my rig is over 6 years old but it still does everything I want it to and I have no reason to upgrade.
i7 isn’t a processor family its a marketing segment. Every generation of intel CPU has a i3 i5 i7. i7 means you have a nicer version of whatever year processor you have but you could have something 14 years old or released yesterday. I know it is absolutely confusing and awful and it makes it very hard to compare different generations without a spec sheet and benchmarks.
Yeah, i7’s (along with i5’s and i3’s) from the 1st to 7th gen aren’t supported, 8th gen has mixed support.
They still run 11 just fine in practice, but installation isn’t as straightforward.
