Microsoft removed Intel's 8th, 9th, and 10th gen CPUs from their supported CPU list. This may or may not matter -- they could have screwed up [wouldn't be a 1st], or it may just reflect Intel moving the now absent CPUs to legacy support. Or it could mean that to upgrade or install Win11 you need to use Rufus to copy an ISO to a USB stick and do its thing to remove hardware checks.
Microsoft has published its latest Windows 11 processor support lists. The latest version of the OS, Windows 11 version 24H2, now includes official support for some of the newest Intel chips such as Lunar Lake and Arrow Lake Core Ultra 200 parts. However, we are surprised to see that Intel's 8th, 9th, and 10th Gen processors are no longer officially supported. The decision may be related to Intel's move of 7th-10th Gen iGPUs to a legacy support model in December.
