Relying on Windows 10 extended support? Time to upgrade

Are you still running Windows 10 because “it’s fine for now”?

I hear that a lot. 

And to be fair, if you signed up for Extended Security Updates (ESU) program, Windows 10 probably does still feel fine. It turns on. It works. It gets security updates. No drama.

But that feeling of safety is temporary.

Windows 10 officially reached the end of standard support back in October 2025. ESU was always meant to be a short-term safety net, not a long-term strategy. 

And that net disappears in October 2026. After that point, Windows 10 stops receiving security updates altogether.

No patches. No fixes. No safety net.

What’s interesting is how many people are still putting this decision off. 

Data shows that millions of PCs are still running Windows 10. Even in regions where support deadlines are well known. 

Now, that data focuses on home users, but in my experience, many businesses are behaving the same way. They’re sticking with Windows 10 because it’s familiar and still technically supported.

And Microsoft hasn’t exactly made that decision feel urgent. 

The same screen that warns you about the end of support also makes it very easy to enroll in ESU. One click, accept the terms, and you can carry on. For a lot of people, that feels like the problem has been solved.

It hasn’t.

ESU only buys you time. Once October 2026 passes, staying on Windows 10 means running an operating system with known vulnerabilities and no protection against newly discovered threats. 

From a business point of view, that’s more than a technical risk. It’s a commercial one. 

Cyber insurance, compliance requirements, and supplier expectations increasingly assume supported software.

At that stage, you’re left with two options: Upgrade to Windows 11 or replace the device entirely.

This is where planning matters. Some older PCs simply won’t support Windows 11. Others will but may need configuration changes or performance checks. 

Leaving this until the last minute often leads to rushed purchases, unhappy staff, and unnecessary costs.

If you’re relying on extended support today, it should be part of a clear exit plan, not a holding pattern.

Because when ESU ends, Windows 10 drops off a cliff.




If you’re unsure whether your current PCs can upgrade or whether you’re heading for a last-minute hardware scramble, now’s a good time to review your options and plan the next step properly.
