Windows 11 24H2 Support Ends Oct 13: Get the Free 26H2 Update Now (What's New)

Every October, Microsoft quietly retires one version of Windows 11 for home users. Most people never notice, because Windows Update nudges them along. This year the timing is tight: the replacement only became available on 29 September, and the cut-off for 24H2 lands two weeks later, on the October Patch Tuesday itself.

The good part? This is about the least painful version upgrade Windows has ever had. No 4 GB download, no hour-long “Working on updates” screen, no reinstalling apps. Below, I’ll walk through exactly who needs to act, how to check your version in ten seconds, the two ways to install 26H2, and the new features you’ll actually notice afterwards.

What actually stops on 13 October?

Microsoft calls it “end of servicing”. In plain terms: the monthly cumulative update that lands on the second Tuesday of each month arrives one last time on 13 October, and then the tap closes for 24H2 Home and Pro. No new security fixes, no bug fixes, no optional preview updates.

Your PC won’t lock up, nag you with a watermark, or stop booting on 14 October. It’ll keep working exactly as it does now. The risk builds slowly: every vulnerability Microsoft patches from November onwards stays open on your machine, and attackers read those patch notes too.

Dates come from Microsoft’s Windows 11 lifecycle tables (checked 2 October 2026).

One more group worth flagging: Windows 11 SE (a stripped-down edition found on some education laptops) tops out at 24H2. This only applies to devices actually running Windows 11 SE: they get their last updates this October with no newer version to move to.

Step 1: Check which version you’re on (10 seconds)

Press Win + R, type winver and hit Enter. A small window pops up showing your version and OS build.

• Version 24H2 / build 26100.xxxx — you need to act before 13 October.
• Version 25H2 / build 26200.xxxx — you’re safe until October 2027, but 26H2 is the same quick install.
• Version 26H2 / build 26300.xxxx — you’re done. Windows already moved you.
• Version 26H1 / build 28000.xxxx — see the note further down; this one can’t jump to 26H2.

Why this upgrade is so small

Think of 24H2, 25H2 and 26H2 as the same house with different rooms unlocked. All three sit on one shared codebase, and over the past year Microsoft has been sneaking the 26H2 bits onto your PC through regular monthly updates — switched off.

The “enablement package” (Microsoft’s term, KB5121794) is basically the key. It’s a tiny file (the x64 .msu on Microsoft’s Update Catalog is listed at roughly 174 KB) that flips those features on and bumps your build number from 26100 or 26200 to 26300. That’s why the install feels like a regular Patch Tuesday update rather than a full Windows upgrade, and why your apps, files and settings don’t move an inch.

Step 2: Get 26H2 through Windows Update (easiest)

This is the route I’d recommend to almost everyone, because Windows only offers the update once it has checked your drivers and hardware against known issues.

1. Save your open work. You’ll need one restart.
2. Open Settings (Win + I) and click Windows Update in the left menu.
3. Click Check for updates and let any regular cumulative updates install first.
4. When you see “Windows 11, version 26H2 is available”, click Download & install next to it.
5. Restart when prompted. Run winver again — you should see build 26300.

Don’t see the offer? The rollout is gradual, so not every PC sees it on day one. Microsoft can also hold the update back on hardware with a known compatibility problem (a “safeguard hold”). If that’s you, give it a few days and check again — and keep the regular cumulative updates flowing in the meantime.

Step 3 (optional): Install KB5121794 manually

Microsoft also publishes the enablement package as a standalone .msu file for both x64 (Intel/AMD) and ARM64 PCs on the Microsoft Update Catalog.

1. Make sure the KB5124010 update (or newer) is installed — see the prerequisite box above.
2. Go to the Microsoft Update Catalog and search for KB5121794.
3. Download the build that matches your processor (x64 for nearly all Intel and AMD PCs, ARM64 for Snapdragon laptops).
4. Double-click the .msu file, confirm, and restart.

What’s new in Windows 11 26H2

Let’s be straight about this: 26H2 doesn’t ship a stack of brand-new, exclusive features. Because 24H2, 25H2 and 26H2 share one codebase, some of what’s listed below may already be on a fully updated 24H2 or 25H2 PC. Other items switch on gradually or need specific hardware (an NPU, a fingerprint reader, a Copilot+ PC). Treat this as the list of features that come with the 26H2 release, not a promise that you’ll see every one the moment you restart. Here’s what stands out from Microsoft’s own changelog.

🧭 Start menu and taskbar you can finally shape

• The reworked Start menu has a scrollable All section with category and grid views, and you can hide the Pinned, Recent or All areas independently.
• The taskbar can sit at the top, bottom, left or right of the screen again — something Windows 10 fans have been asking for since 2021.
• A smaller taskbar option shrinks icon size and bar height, which helps on 13- and 14-inch laptops.

📁 A quicker, smarter File Explorer

• File Explorer Home opens faster and feels more responsive.
• More archive formats open natively, including uu, cpio, xar and .nupkg.
• View and Sort settings now stick in Downloads and Documents, even when an app opens those folders for you.
• You can rename files using voice typing.

🔍 Search that forgives typos

• App search copes with spelling mistakes and half-typed names.
• Results are labelled clearly as an app, setting, file, web result or Store suggestion, and you can preview them without opening anything.

🛡️ Security upgrades under the hood

• Smart App Control can now be turned on or off without a clean reinstall of Windows — a long-standing annoyance, gone.
• Passkeys work with third-party password managers that plug into Windows.
• Windows Hello Enhanced Sign-in Security now supports compatible external fingerprint readers, not just built-in ones.
• Default trust for old cross-signed drivers is removed. Windows audits driver compatibility first (at least 100 hours and three restarts) before enforcing the change.
• Sysmon is built in, and Administrator protection is available — both off by default and aimed mainly at IT admins.

🔧 Everyday fixes you’ll feel

• Fewer update restarts: Windows Update bundles eligible updates with the monthly security patch when it can.
• Point-in-time restore can roll a PC — apps, settings and files — back to a recent automatic restore point.
• Better Bluetooth (LE Audio, calls, reconnecting after hibernation) and steadier USB4 dock displays after sleep.
• Several apps can use the webcam at once with Multi-App Camera.
• Task Manager shows NPU usage on PCs that have one.
• Accessibility gets a lot of love: Magnifier colour tints and custom zoom levels, a Braille Viewer in Narrator, and Voice access in French, German, Spanish and Korean.

🗑️ What’s gone

WMIC, the old Windows Management Instrumentation command-line tool, is removed and no longer offered as an optional feature. If you have old batch scripts that call wmic, switch them to PowerShell’s Get-CimInstance before upgrading.

Special cases: 26H1 PCs, Enterprise and older hardware

Bought a new Arm laptop this year? Some ship with Windows 11 26H1 (build 28000), which runs on a different core. Those machines can’t move to 26H2 — and they don’t need to. Windows 11 26H1 Home and Pro are supported until 14 March 2028, and Enterprise and Education until 13 March 2029. That’s a shorter window than 26H2 gets, and Microsoft says it will offer them a path to a later release.

On Enterprise or Education? You have until 12 October 2027 on 24H2. Your IT team can push 26H2 through Windows Autopatch, Intune or the Microsoft 365 admin center when they’re ready. Note that 26H2 turns on Windows settings backup, taskbar app actions and some File Explorer changes by default on commercial devices.

Running 24H2 on a PC that doesn’t officially meet Windows 11 requirements? Windows Update may not offer you 26H2 automatically. The manual package route works on the same codebase, but you’re outside Microsoft’s support boundaries, so back up first.

A 5-minute pre-flight checklist

An enablement package is about as low-risk as Windows updates get, but a little prep never hurts:

• ✅ Back up anything irreplaceable to OneDrive or an external drive.
• ✅ Plug in the laptop charger.
• ✅ Update your graphics, chipset and Wi-Fi drivers — our guide to free driver updaters for Windows 11 covers safe options, including Windows Update’s own Optional updates page.
• ✅ If you use a script that calls wmic, update it.
• ✅ After the restart, run winver to confirm build 26300.

Once you’re on 26H2, it’s a good moment to run through our Windows 11 security settings you should switch on — especially now that Smart App Control can be toggled without a reinstall. And if the PC still feels sluggish afterwards, our 9 proven ways to make Windows 11 faster all carry over to 26H2, since it runs on the same core.

If something goes wrong

• Package refuses to install: you’re almost always missing the KB5124010 (or newer) cumulative update. Install it, restart, try again.
• Build says 26300 but features look unchanged: some features still roll out gradually after the version bump. Keep installing monthly updates.
• Something broke: Settings → System → Recovery lets you go back to the previous version for a limited time after a feature update. Check Microsoft’s Windows release health page for known issues before you roll back.
