You know that friend who refuses to leave a party, even after the lights come on and the host is yawning? That's Windows 10. And Microsoft, ever the gracious—or desperate—host, just pulled out another chair.
On Thursday, Microsoft announced it's adding another year to Windows 10's Extended Security Updates (ESU) program. Translation: If you're still clinging to that aging PC with Windows 10, you can buy another year of security patches. This is the second extension for a program that was supposed to end in 2025. Now it runs through October 2026. Some analysts suspect it won't end then either.
Because here's the problem: About a quarter of all PCs are still running Windows 10. That's roughly 400 million machines, give or take. And many of them belong to businesses that would rather pay Microsoft than deal with the headache of replacing hardware or retraining staff on Windows 11.
The Numbers Don't Lie
According to data from Statcounter, Windows 10's market share has hovered around 25% for months. That's down from 70% in 2021, but it's still a massive chunk. Windows 11 sits at about 68%. The remaining 7% is a graveyard of Windows 7, 8, and various Linux flavors.
Here's what's driving the stickiness: Windows 11 requires a TPM 2.0 chip and relatively recent CPUs. Millions of perfectly functional PCs from 2018 or earlier can't upgrade. For cash-strapped schools, small businesses, and government agencies, replacing a fleet of machines isn't in the budget. So Microsoft gets to charge them per device for extended updates—$61 per seat for the first year, doubling each subsequent year.
Microsoft is making a fortune off people who can't afford to upgrade. It's brilliant. It's also predatory.
Is it cynical? Sure. But it's also pragmatic. Microsoft knows that pushing too hard would alienate customers. So they offer a paid bridge. Critics call it a tax on the poor. Microsoft calls it a service.
What This Means for Your Business
If you're an IT manager, this extension changes your calculus. You now have until October 2026 to migrate—or pay up. But here's the kicker: Microsoft has already extended the program twice. There's no guarantee this is the last time. Some companies will gamble on another extension, delaying the inevitable upgrade. That's risky. Each year you wait, the cost multiplies, and the security risk grows.
Also consider: Windows 10 won't receive feature updates. Only security patches. So while your machine stays safe from the latest zero-day, it also stays stuck in 2025's interface. No new features. No performance improvements. Your competitors using Windows 11 will get faster file systems, better multitasking, and AI integration. You'll get a patch for a printer driver exploit.
For individuals, the ESU program isn't available. So if you're a home user still on Windows 10, you're out of luck after October 2025—unless Microsoft changes its mind. And given this week's news, don't bet against it.
The Real Story: PC Stagnation
This extension is a symptom of a larger problem: PC sales are flat. IDC reported a 2% decline in PC shipments in 2025. People are holding onto their devices longer. Why? Because the incremental upgrades aren't compelling. A 2023 laptop does everything a 2025 laptop does, just a bit slower. Windows 11's main selling point—better security—is undermined by the fact that Windows 10 still gets patched.
Microsoft knows this. They're trying to break the cycle with Windows 12, reportedly due in 2027. But until then, they're stuck managing the decline of their cash cow. The ESU program is a Band-Aid. It generates revenue but signals weakness.
Meanwhile, Apple is eating Microsoft's lunch. Mac market share has climbed to 15% in the US, driven by the M-series chips. Google's Chromebooks are dominant in education. Microsoft needs Windows 11 to succeed, but it can't afford to anger the 25% who won't budge.
What You Should Do
If you're on Windows 10, you have options. Option one: Upgrade to Windows 11. Most PCs from 2020 or later can do it, even if Microsoft's compatibility checker says no. There are workarounds. Option two: Buy extended support for your business. Option three: Switch to Linux. It's free, it's secure, and it runs on ancient hardware. But good luck explaining that to your boss.
Do not just ignore the deadline. Unpatched Windows 10 machines are a hacker's dream. Remember WannaCry? That hit old systems. Attackers are already stockpiling exploits for October 2025.
Microsoft's decision to extend is a gift and a warning. It's a gift because you have more time. It's a warning because that time is running out. And Microsoft is betting you'll pay for the privilege of ignoring reality.
Don't take that bet.
