Windows 10 Still Haunts One in Six Enterprise PCs, Because Apparently Misery Loves Company

Right then, here’s the grim little update from the corporate Windows swamp: despite Microsoft banging the drum for everyone to get the hell onto Windows 11, about one in six enterprise PCs are still dragging around Windows 10 like a half-dead mule in a server room. Support for Windows 10 is circling the drain, and yet loads of businesses are still sitting there pretending the problem will magically piss off on its own.

The article points out that Windows 11 adoption has been climbing, which is hardly shocking since Microsoft has spent the last few years nagging, shoving, and generally being a pain in the arse about it. Even so, a stubborn chunk of enterprise machines haven’t moved. Why? Because enterprise IT is full of ancient hardware, crap compatibility requirements, budget excuses, and the timeless tradition of management saying, “Let’s deal with that later,” right up until later becomes a catastrophic dumpster fire.

A lot of these PCs can’t officially run Windows 11 because of the stricter hardware requirements, especially around TPM and newer CPUs. So now organisations get to enjoy the consequences of years of penny-pinching: fleets of perfectly “fine” machines that are suddenly too old for the new shiny OS. Funny how “we’ll save money by delaying refresh cycles” turns into “holy shit, why do we need to replace hundreds of devices at once?”

The piece also hammers home the obvious: once Windows 10 support expires, keeping those systems around becomes a security and compliance headache. And no, hoping attackers won’t notice your unsupported endpoints is not a strategy, it’s just professional negligence wearing a cheap tie. Companies can pay for extended security updates, of course, because there’s always another bloody invoice waiting when you fail to plan properly.

Meanwhile, Windows 11 is gaining ground across enterprises, but not nearly fast enough to avoid the usual last-minute migration panic. You know the one: executives ignore repeated warnings for years, then suddenly demand a flawless transition in three weeks because someone important read a scary memo. Then IT gets blamed when the whole thing turns into a screaming shitshow involving procurement delays, broken apps, and users who think rebooting is a human rights violation.

So the takeaway is simple: Windows 10 is still hanging on in a significant slice of enterprise environments, not because it’s some beloved masterpiece, but because corporate inertia is one hell of a drug. The deadline is coming, the hardware problem is real, and every day wasted now just means more pain, more cost, and more swearing later. Which, to be fair, is job security for the rest of us miserable bastards.

Anecdote time: I once watched a department ignore upgrade warnings for so long that when the cutoff finally hit, they tried to argue that their ancient PCs were “mission critical.” They were. Mission critical to printing stale spreadsheets and jamming every other Tuesday. We replaced the lot over a weekend while management acted shocked—shocked!—that neglecting shit for five years had consequences. Morons.
