Windows 11 24H2 goes from “unsupported” to “unbootable”

[Biterider]

[...]
That's apparently changing a bit in Windows 11's 24H2 update, which Microsoft began testing earlier this month. According to posts from a user named Bob Pony on X, formerly Twitter, the latest Windows 11 builds refuse to boot on older processors that don't support a relatively obscure instruction called "POPCNT."

PopCount() runs on all CPUs and is almost as fast as the native popcnt instruction that you may find on recent CPUs

Memories... that was 8 years ago, but popcnt is actually a bit older:

Intel implements POPCNT beginning with the Nehalem microarchitecture

almost 16 years ago. I thought Windows 11 required a recent cpu to be installed?

Yet another reason, if any were needed, to avoid Windows 11 like the plague.

A comment from that article (by someone with the handle "Frodo Douchebaggins"):

I will continue my journey of avoiding Windows 11 for as long as I possibly can, which is hopefully forever.

Hi NoCforMe,

A home user can do it but no way for an IT department. Sadly, companies will have to move to Windows 11.

Perhaps not a problem for companies, as they change desktop PC's more often than i change trousers

Well, sure: companies are locked into the never-ending cycle which necessitates having the "latest and greatest" of both hardware and software on their desktops and in their server rooms. They won't fight this, and in fact just treat it as one of their ongoing expenses.

Hello,

Not every company is purchasing immediately the latest hardware after the release of a new operating system. Most of the Win10 laptops are supporting Win11. Today's conditions are different especially after the C19 pandemic.
