Windows 11 24H2 Support Ends October 13, 2026: 25H2 or 26H2, and Why the Update Isn’t Showing Up

Eleven days. That’s how long a Windows 11 PC still on version 24H2 has left on its security updates, counting from today, October 2, 2026.

The PC won’t stop booting on October 14. Nothing visible changes. It just stops getting the monthly patches, and that’s the kind of problem nobody notices until something gets through.

The good news is that this upgrade is small. Here’s how to check where you stand, which version to pick, and what to do when Windows Update refuses to offer anything.

Am I Still on Windows 11 24H2?

To check your Windows 11 version, press Windows + R, type winver, and press Enter: the window shows a line such as “Version 24H2 (OS Build 26100.xxxx),” and any 24H2 build number starts with 26100.

The build prefix is the quickest tell:

• 26100.xxxx — version 24H2. This is the one losing support.
• 26200.xxxx — version 25H2.
• 26300.xxxx — version 26H2.

You’ll also see the edition in Settings > System > About. If it says Enterprise or Education, the October 13 date doesn’t apply to you. Those editions of 24H2 run until October 2027.

What Actually Stops on October 13, 2026?

After October 13, 2026, Windows 11 version 24H2 Home and Pro devices no longer receive monthly security updates, preview updates, fixes for known issues, time zone updates, or technical support, according to Microsoft’s Windows 11 24H2 release health page.

Your apps keep working. Your files stay put.

What you lose is the patch for the next Windows flaw. That’s the part that matters.

Microsoft’s same page says unmanaged Home and Pro devices on 24H2 “will receive the Windows 11, version 25H2 update automatically.” So many PCs will move on their own. The ones that don’t are usually held back by something, and that’s covered below.

Should I Install 25H2 or Jump Straight to 26H2?

Windows 11 version 26H2, released on September 29, 2026, can be installed directly on 24H2 as an enablement package and gives Home and Pro editions 24 months of support, about one year more than 25H2, according to Microsoft’s How to get the Windows 11 2026 Update post.

When I compared the end dates on Microsoft’s Windows 11 Home and Pro lifecycle page, the gap was clearer than most coverage makes it sound:

Table: release and end dates from Microsoft’s Windows 11 Home and Pro lifecycle page (Pacific Time) as of October 2, 2026; the “months left” column is our own count.

So which one? Here’s the short version:

• Pick 26H2 if it’s offered and you want to skip this whole exercise next October.
• Pick 25H2 if your PC runs software that’s picky about new Windows builds, or if 26H2 simply isn’t offered yet. You’ll do this again in 2027.
• Take whatever shows up first if you’re short on time. Either one gets you past October 13.

Honestly, the version matters less than getting off 24H2.

How Do I Get the Update Through Windows Update?

To get Windows 11 version 25H2 or 26H2 on a 24H2 PC, open Settings > Windows Update, turn on “Get the latest updates as soon as they’re available,” select Check for updates, and choose Download and install when the feature update appears.

Step by step:

1. Install pending updates first. The enablement package needs the latest monthly cumulative update underneath it. If Windows Update shows anything waiting, install it and restart.
2. Turn on the toggle. In Settings > Windows Update, switch on “Get the latest updates as soon as they’re available.” Microsoft’s 26H2 post names this toggle as the way to see the offer early.
3. Check for updates. Look for “Windows 11, version 26H2” or “version 25H2” with a Download and install link. It sits apart from the regular monthly update.
4. Restart once. An enablement package switches on features already on disk, so it usually needs one restart and takes minutes, not an hour.
5. Confirm it worked. Run winver again. The build should now start with 26200 or 26300.

Most people skip step 1 and wonder why nothing shows up.

Why Isn’t 25H2 or 26H2 Showing Up for Me?

When Windows Update shows a message like “Upgrade to Windows 11 is on its way to your device. There is nothing that requires your attention at the moment,” a safeguard hold is usually blocking the feature update because Microsoft detected a known compatibility issue with a driver or app on that PC, according to Microsoft support article KB5006965.

That message has a Learn more link. Click it. It opens a page listing the holds that apply to your specific device, if any.

Here’s how the common causes line up:

Table: our own symptom-to-cause summary, based on Microsoft’s KB5006965 safeguard hold guidance and Windows Update settings as of October 2026.

That third row catches more home users than you’d expect. If you ever used a guide that set a “target release version” in Group Policy or the registry to stay on 24H2, Windows will keep obeying it. Look under Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage updates offered from Windows Update and set “Select the target Feature Update version” back to Not Configured.

Known Issues Worth Checking Before You Click Install

Several of the September 2026 problems on Microsoft’s release health list also affect 25H2 and 26H2, so upgrading doesn’t make them go away.

I noticed that the USB audio entry, where some USB Audio Class 1.0 headsets and DACs show “Code 10,” lists 26H2 among its affected versions and was still marked only “Mitigated” when the page was last updated on September 29, 2026. If you rely on an older USB DAC, read Microsoft’s entry before you move.

Two more to be aware of:

• Black screen after sign-in. Seen mostly on Azure Virtual Desktop hosts with FSLogix, not typical home PCs. Microsoft’s workaround is to open Task Manager, choose Run new task, and start explorer.exe.
• Domain trust failures. Only affects PCs joined to an on-premises Active Directory domain with Credential Guard machine accounts. Home users can ignore it.

None of these is a reason to stay on 24H2 past October 13. They’re a reason to have a backup.

Tips

• Make a restore point or a quick File History backup before any feature update, even a small one.
• Update graphics, audio, and Wi-Fi drivers from the PC maker’s site first. Old drivers trigger most safeguard holds.
• Keep about 10 GB free on the system drive so the update has room to stage.
• Write down the build number before and after. It makes any support conversation faster.

Warnings

• Don’t bypass a safeguard hold with an ISO or the Installation Assistant unless you’ve read what the hold is for. It exists because a known problem hits your hardware.
• Be careful with “stay on 24H2” registry tweaks from old forum posts. After October 13 they keep you on an unpatched version.
• Within 10 days of an upgrade you can usually roll back from Settings > System > Recovery. After that, the option disappears.

FAQ

Will my PC stop working after October 13, 2026 if it stays on 24H2?

No. A Windows 11 24H2 PC keeps booting and running apps after October 13, 2026. It just stops receiving monthly security updates, bug fixes, and support from Microsoft.

Is upgrading from 24H2 to 25H2 or 26H2 free?

Yes. Both are free feature updates delivered through Windows Update. On a 24H2 PC they install as a small enablement package with one restart.

Does Windows 11 Enterprise 24H2 also lose support in October 2026?

No. Enterprise and Education editions of 24H2 get 36 months of servicing, so they are supported until October 2027. Only Home and Pro end on October 13, 2026.
