According to Windows Report | Error-free Tech Life, Microsoft has acknowledged a Windows 10 bug that’s falsely telling users their version has reached end of support. The issue started appearing after installing updates released on or after October 14, 2025, specifically KB5066791. It affects Windows 10 version 22H2 Pro, Education, and Enterprise editions enrolled in Extended Security Updates, plus some LTSC versions. Microsoft says it’s just a display error – affected devices will still get security updates normally despite the scary warning.

Why This Actually Matters
Here’s the thing – when Windows starts flashing “end of support” warnings, people panic. And they should! That message basically means “you’re about to become vulnerable to every hacker on the internet.” So even though Microsoft says it’s just a display bug, this kind of error shakes user confidence in a major way.
Think about it from an enterprise IT perspective. How many help desk tickets do you think this generated overnight? How many CIOs got urgent calls from executives who saw that warning on their laptops? The timing couldn’t be worse either – we’re in that awkward transition period where businesses are supposed to be moving to Windows 11 but many are clinging to Windows 10 through Extended Security Updates.
The Bigger Competitive Picture
This mess actually plays right into the hands of Microsoft’s competitors. When enterprise customers see Windows acting up like this, they start seriously considering alternatives. Linux distributions are looking more stable by comparison. ChromeOS for business is suddenly more appealing. Even macOS starts seeming like the safer choice for companies tired of Windows update drama.
And let’s talk about the Extended Security Updates program itself. Companies are paying Microsoft good money for these updates – we’re talking $61 per device for the first year, doubling each subsequent year. When you’re paying premium prices for “extended security” and then get false alarms about support ending, it makes you question the value proposition. Basically, Microsoft is charging extra for what feels like a less reliable experience.
The real winner here might be Windows 11, ironically. Every time Windows 10 has a public stumble like this, it gives Microsoft more ammunition to push the “upgrade to Windows 11” narrative. But that creates its own problems – many businesses have hardware that can’t run Windows 11, or they’ve standardized on applications that aren’t compatible yet. So they’re stuck between a buggy Windows 10 and an upgrade path that doesn’t work for them.
At the end of the day, this is more than just a display bug. It’s a symptom of Microsoft’s complicated Windows support strategy creating confusion in the market. And when you’re dealing with enterprise customers who need stability above all else, that confusion has real business consequences.
