Windows 11 23H2 Just Got Its Final Update - How to Check Your PC and Upgrade for Free

Windows 11 23H2 has received its last update - if your PC still runs it, here is how to check in ten seconds and move to a supported version for free.

The final update is called KB5131087, and it arrived on 10 November 2026.

It is the last one for Enterprise and Education editions - Home and Pro already stopped getting updates in November 2025.

Your PC keeps working, but from now on any new security hole stays open.

Are You on 23H2? The Ten-Second Check

Press Win + R, type winver and press Enter. A small box shows your version and build number.

• Build starts with 22631: you are on 23H2 and need to move on.
• Build starts with 26100, 26200 or 26300: you are on 24H2, 25H2 or 26H2, and this news does not affect you.

What Microsoft Actually Said

Microsoft's KB5131087 release notes put it plainly: "Windows 11, version 23H2 Enterprise and Education have reached end of updates." The November security update is "the last update available for these editions."

Version 23H2 first shipped in October 2023. Home and Pro got two years of support, and work and school editions got three - that third year is what ended this week.

Install KB5131087 anyway if it is waiting for you. It fixes an error 87 when adding some network printers, turns on extra network sign-in protection, and Microsoft lists no known problems with it.

Which Version Should You Move To?

Skip 24H2 - Home and Pro support for it already ended in October. Pick 25H2 or 26H2, which run the same apps and differ mainly in how long they are supported.

Our pick is 26H2, simply for the extra year. One thing to know: coming from 23H2, this is a full upgrade rather than a quick one-restart switch, so allow about an hour.

How to Upgrade From 23H2 for Free

Back up anything you can't replace first. The upgrade keeps your files and apps, but a backup costs ten minutes and saves a bad day.

1. Try Windows Update first. Press Win + I, open Windows Update and click Check for updates - if a newer version is offered, click Download and install.
2. Nothing offered? The free Windows 11 Installation Assistant installs the newest version over 23H2 and keeps your files, apps and settings.
3. Prefer an ISO or a USB stick? Our 26H2 download guide covers every route, step by step.
4. Check it worked. Run winver again - a build starting with 26300 means 26H2, and 26200 means 25H2.

If the Upgrade Won't Go Through

Windows says your PC is not supported. This is the most common reason a home PC is still on 23H2 - Windows 11 was installed on older hardware, so Windows Update never offers newer versions. Our Rufus guide for unsupported PCs walks you through it with the free Rufus USB tool.

Windows Update keeps saying nothing is available. Microsoft sometimes holds back an upgrade on PCs with a known driver or app conflict. Install every pending update, restart, and check again after a few days before forcing it.
