Windows 11 24H2 End of Support: What Carrum Downs & Frankston PC Owners Need to Do Before 13 October 2026
If your Windows 11 laptop or desktop has been nagging you about an update lately, there's a real deadline behind it. Microsoft has confirmed that Windows 11, version 24H2 (Home and Pro editions) stops receiving security updates on 13 October 2026 — one month from today. After that date, Microsoft no longer ships security patches, bug fixes or technical support for 24H2, even though the PC itself will keep running.
This isn't the same story as Windows 10's end of support, which we've covered separately. It's a smaller, quieter deadline that catches a lot of people off guard because their PC still says "Windows 11" and looks fine — it's the specific version number underneath that has expired.
What "end of support" actually means for Windows 11 24H2
Version 24H2 will keep booting, keep opening your files, and keep looking exactly the same after 13 October 2026. What stops is the flow of monthly security patches. Every month, Microsoft closes newly discovered vulnerabilities in Windows — this month's Patch Tuesday alone fixed two flaws that were already being actively exploited (see our September 2026 Patch Tuesday article). Once 24H2 stops getting those fixes, any newly discovered vulnerability stays open indefinitely — on a machine that's usually connected to email, banking, and business systems.
Which PCs are affected
Home and Pro editions — support ends 13 October 2026
This covers the vast majority of home and small-business PCs running Windows 11 24H2. If your device was set up or updated sometime after late 2024, there's a good chance it's on this version.
Enterprise and Education editions — an extra year, until 13 October 2027
Businesses running Enterprise or Education licensing get a longer runway. Most of Macrotech's residential and small-business customers are on Home or Pro, so the October 2026 date is the one that matters for most people reading this.
How to check which Windows 11 version you're running
- Press the Windows key, type winver, and press Enter — a small window will show your exact version (e.g. "24H2", "25H2").
- Or go to Settings → System → About and look for "Windows specifications."
- If you see 24H2, keep reading. If you see 25H2 or 26H2, you're already on a supported version and don't need to do anything right now.
Your three options before 13 October 2026
Option 1: Upgrade in place to a newer version
For most PCs, this is a free, in-place update through Windows Update (Settings → Windows Update → Check for updates). Microsoft has been progressively rolling 24H2 devices onto 25H2, and version 26H2 entered its Release Preview testing phase on 27 August 2026, with a wider general release expected in the following weeks. If your PC is offered 25H2 or 26H2 through Windows Update, taking it resets your support clock and typically takes 20–40 minutes.
Option 2: Extended Security Updates (ESU), if available for 24H2
Microsoft has previously offered paid or conditional ESU programs for versions nearing end of support (as it did for Windows 10). Whether — and on what terms — an ESU path exists for 24H2 specifically should be confirmed directly on Microsoft's official support site closer to the deadline, as terms can change. We'll update this article if Microsoft confirms an ESU option for 24H2.
Option 3: Get your PC assessed if it won't upgrade cleanly
Some PCs fail to install the newer version because of driver conflicts, insufficient storage, a failing SSD, or hardware that's borderline for Windows 11's requirements (TPM 2.0, Secure Boot, supported CPU generation). If Windows Update keeps failing or getting stuck, that's usually a sign of an underlying issue rather than something to keep retrying indefinitely.
Why some PCs don't upgrade smoothly
In our workshop, failed feature updates are most often caused by one of a handful of things: a nearly-full or ageing hard drive/SSD, corrupted system files from a previous interrupted update, incompatible or outdated drivers, or hardware that technically meets Windows 11's minimum spec but struggles under a large in-place upgrade. None of these are unusual, and most are fixable without losing your files — but repeatedly retrying a failing update on a struggling drive can make things worse, not better.
What actually happens if you do nothing after 13 October
Your PC won't shut off or stop working. But every month afterward, it becomes a slightly larger target: no patches for newly found Windows flaws, increasing incompatibility with new software and drivers over time, and — for many households and small businesses — a growing gap between "it still turns on" and "it's still safe to bank, shop or store client data on."
How this connects to this month's record Patch Tuesday
This deadline lands right after Microsoft's largest Patch Tuesday of the year, which fixed two Windows flaws that attackers were already exploiting (read the details in our September 2026 Patch Tuesday breakdown). It's a useful reminder of exactly what "no more security updates" will mean for 24H2 devices from mid-October: months like this one, with zero patches.
Local help in Carrum Downs, Frankston and southeast Melbourne
If you've checked your version, tried Windows Update, and it's stuck — or you're simply not confident doing it yourself — Macrotech can check your PC's health, run the update safely with your files backed up first, and flag if there's a hardware issue (failing drive, tired battery, overheating) worth fixing at the same time. We work on both Mac and Windows laptops and desktops for customers across Carrum Downs, Frankston, Cranbourne, Lyndhurst, Langwarrin, Seaford, Skye, Patterson Lakes and the surrounding southeast Melbourne suburbs.

Do I need to buy a new PC when 24H2 support ends?
Not necessarily. Most 24H2 PCs simply need to update to a newer Windows 11 version through Windows Update, which is free. A new PC is only worth considering if your current one is genuinely old, struggling to run 25H2/26H2, or has an unrelated hardware fault.
What's the difference between 24H2, 25H2 and 26H2?
They're all Windows 11 — 25H2 and 26H2 are simply newer annual feature updates. Each one resets the support clock for another roughly two years (Home/Pro) from its own release date. The version number tells you how current your security support is, not which "Windows" you're running.
Will my computer stop working on 13 October 2026?
No. It will keep running exactly as before. What stops is Microsoft's supply of new security patches and technical support for that specific version, which increases risk over time rather than causing an immediate failure.
What if Windows Update won't let me upgrade past 24H2?
This usually points to a storage, driver or hardware issue rather than something you should keep force-retrying. Backing up your files and having the update run and the PC assessed together is the safer approach.
Is this the same as the Windows 10 end-of-support deadline?
No — that's a separate, larger deadline affecting a different operating system generation. See our Windows 10 end-of-support guide if you're still running Windows 10.
