Windows 11 24H2 End of Life: The Real Deadline (October 13, 2026)

Just when you thought you were done worrying about Windows going end of life, it’s happening again — and this time it’s not even Windows 10.

If you’re running Windows 11, there’s a version number buried in your settings that has its own expiration date. And depending on which one you’re on, that date might be a lot closer than you think.

Update (September 30, 2026): Microsoft released Windows 11 version 26H2 on September 29, 2026. It’s available for PCs on 24H2 and 25H2 as a small update with one restart, and it’s rolling out gradually. If you’re on 24H2, moving to either 25H2 or 26H2 keeps you supported past October 13. Want it sooner? Go to Settings → Windows Update and turn on “Get the latest updates as soon as they’re available.”

Windows 11 Isn’t One Thing — It’s a Moving Target

Here’s the part that trips people up: “Windows 11” isn’t a single product with one end-of-life date. Every feature update — 23H2, 24H2, 25H2, and whatever comes next — is basically its own mini operating system with its own clock running.

23H2 already went end of life. 24H2 is next, on October 13, 2026. 25H2 follows it in October 2027. Whatever version you installed, you didn’t just install “Windows 11” — you installed a specific version of it, with an expiration date baked in from day one.

Who’s Actually Affected

This one hits Home and Pro editions. If that’s you, the October 13, 2026 deadline applies.

Enterprise and Education editions get one additional year of support on top of that. If you’re on one of those editions through work or school, you’ve got more runway — but the clock is still ticking, just on a longer fuse.

How to Check Which Version You’re Running

Most people genuinely don’t know. Here’s the fastest way to find out:

1. Press Windows key + R
2. Type winver and hit Enter

Or, if you’d rather click through the menus: Settings → System → About, then scroll down. Either way, that version number is your expiration clock.

What Actually Happens After End of Life

Nothing dramatic. Your PC doesn’t shut off, and nothing breaks overnight. What happens is quieter than that — and worse.

No more security updates. No more bug fixes. No more patches. Any vulnerability discovered after October 13, 2026 stays open on an unsupported 24H2 machine, permanently.

It doesn’t stop at Windows itself, either. Browsers eventually drop support for older versions. Security software starts losing compatibility. Drivers stop getting updated. Your system doesn’t just get outdated — it slowly becomes incompatible with everything around it. And unsupported systems are exactly what attackers look for first, because they know precisely what isn’t getting patched anymore.

You Can Delay This — You Can’t Avoid It

If you’re on Home or Pro, you don’t have long-term control here. You can pause updates. You can push them off for a while. But eventually, if your system is eligible, Windows Update is going to move you forward whether you click “yes” or not.

That’s not Microsoft being difficult for the sake of it — updates do patch real vulnerabilities and fix real problems. But let’s be honest: not every update makes things better. Drivers break. Software stops working. Performance tanks sometimes. That’s exactly why doing this on your terms, before you’re forced into it, is always the better move.

The Full Timeline

• 23H2 — already end of life
• 24H2 — end of life October 13, 2026
• 25H2 — end of life October 2027
• 26H2 — released September 29, 2026; supported for 24 months on Home and Pro

Microsoft hasn’t locked in every future date yet, but if the pattern holds — and it has every time so far — expect a new version to show up right around the time each one expires. This cycle isn’t stopping.

If you’re also still sitting on an actual Windows 10 machine, that’s a related but separate deadline — worth reading what changed with Windows 10’s Extended Security Updates too.

What To Do About It

Staying on 24H2 past the deadline is technically possible. It’s just not the smart move — you’d be running with no security coverage on a machine still connected to the internet.

If you’re planning to move forward, don’t go in blind. That’s exactly what my Ultimate Windows Survival System covers — what to check before you upgrade, how to avoid breaking things in the process, and how to fix it if something does go wrong anyway.

And remember my friends… stay grumpy.
