If your PC still runs Windows 11 version 24H2, an important date has already passed, and it is worth checking your version today rather than waiting for something to go wrong. For Home, Pro, Pro Education and Pro for Workstations editions, Microsoft lists version 24H2 as having reached end of updates, with 13 October 2026 as the cut-off. That does not mean your computer stops working. It does mean that, from that date, those editions no longer receive the monthly security and quality updates that patch newly discovered problems. The next monthly security release for supported versions falls on Tuesday 10 November 2026, the second Tuesday of the month, and a PC still on 24H2 Home or Pro will not get it.

This guide explains what actually ended, who is affected and who is not, how to check your version in under a minute, and how to move to Windows 11 version 26H2, the free update that restores a full support clock. It also covers what to do if 26H2 has not been offered to your PC yet, and the cases where this particular upgrade path does not apply. There is no need to panic, and there is no need to buy a new PC for this change alone, but leaving a Home or Pro PC on 24H2 indefinitely is a decision with a growing downside, not a neutral one.

What actually ended on 13 October 2026

Windows 11 does not have one single end date. Each version has its own servicing period, and the date depends on both the version and the edition. Microsoft gives Home, Pro, Pro Education and Pro for Workstations 24 months of updates for each version, and Enterprise and Education editions 36 months. Version 24H2 arrived on 1 October 2024, so its 24-month Home and Pro period ran out in October 2026.

Microsoft's Windows 11 release information page now lists 24H2 Home, Pro, Pro Education and Pro for Workstations as "End of updates", while the Enterprise, Education and IoT Enterprise editions of 24H2 remain supported until 12 October 2027. That split is the single most important detail in this story, because two PCs can both say "Windows 11 24H2" and be in completely different positions. A home laptop and a company-managed desktop are not on the same clock.

For the editions whose updates have ended, the October 2026 security update was the last one. After that, Microsoft no longer ships monthly security updates, preview updates, fixes for known issues, time zone updates or technical support for that version and edition. Your files, apps and settings do not disappear, and Windows does not lock you out. What changes is quieter and slower: when a new vulnerability is found and fixed for supported versions, no equivalent fix arrives for 24H2 Home or Pro. Over weeks and months, that gap grows, and it grows fastest for the parts of a PC most exposed to the internet, such as the browser, email and downloaded files. That is why this is best treated as a maintenance job to do soon, not as an emergency and not as something to ignore for a year.

One more distinction matters. Ending updates for 24H2 is not the same as ending support for Windows 11 itself, and it is not the same as the Windows 10 story covered in our earlier post about extended security updates. Windows 11 is still fully supported through newer versions, and the fix here is a free version upgrade on the same PC, not a move to a different operating system.

Who needs to act, and who does not

Check this list before you change anything, because the right next step depends on your version and edition.

You need to act soon if you run Windows 11 version 24H2, Home, Pro, Pro Education or Pro for Workstations edition. That is the group whose updates have ended. If that describes your PC, plan the move to 26H2, described below, and do it before you settle into a routine of skipping monthly updates.

You do not need to rush if you already run Windows 11 version 25H2 or 26H2. Version 25H2 Home and Pro editions receive updates until 12 October 2027, and version 26H2 Home and Pro editions receive updates until 10 October 2028. If you are on either of those, you are already on a supported version, and this deadline does not apply to you.

You do not need to act on this deadline if your PC runs 24H2 Enterprise or Education edition, for example a work or school computer managed by an IT department. Those editions are supported until 12 October 2027. In that case, do not try to force a personal upgrade path on a managed machine; follow your organisation's update schedule instead.

You need a different route, not the one in this guide, if you run Windows 11 version 23H2 or older, or Windows 10. The small enablement package described below works only from 24H2 or 25H2. Older versions need a full feature update, which is a larger download and a longer install, and Windows 10 PCs need to move to Windows 11 first or use the separate extended security update route. Do not assume the quick method will work on an older version.

You also need a different expectation if your PC runs version 26H1. Microsoft says 26H1 is scoped to new devices that started coming to market in early 2026 and is not offered as an in-place update from 24H2 or 25H2 on existing devices. If you bought a brand-new 2026 device and find it on 26H1, the 26H2 enablement package is not your upgrade path; Microsoft says those devices will move to a future Windows release. That is a separate branch, not a failure of Windows Update on your machine.

Check your version in under a minute

Do not guess from when you bought the PC or when you last remember updating. Versions change silently in the background, and many PCs have already moved on without their owners noticing. The check takes less than a minute.

The quickest way is the winver command. Press the Windows key and R together, type winver, and press Enter. A small window shows your Windows edition and version, and the OS build number. The build numbers are a useful cross-check: builds starting with 26100 are version 24H2, builds starting with 26200 are version 25H2, and builds starting with 26300 are version 26H2.

You can also check in Settings. Open Settings, then System, then About, and look for the Windows specifications section, which lists the edition and version. Either method is fine; use whichever you remember more easily.

If the window says 26H2 or 25H2, you can stop here. If it says 24H2, check the edition as well. Home or Pro means you are in the group whose updates have ended. Enterprise or Education means you are covered until October 2027, and a managed PC should stay on its organisation's schedule.

The upgrade: why 26H2, and why it is so quick

For a PC on 24H2 or 25H2, the recommended destination is Windows 11 version 26H2, also called the Windows 11 2026 Update, which reached general availability on 29 September 2026. It is the newer of the two supported destinations, and it gives Home and Pro users updates until 10 October 2028, about a year longer than stopping at 25H2, whose Home and Pro support ends on 12 October 2027. Since both arrive through the same place and by the same method, there is no support reason to stop at the older version if 26H2 is offered to your PC.

The reason the upgrade is quick is that 24H2, 25H2 and 26H2 share a common core operating system with an identical set of system files, in Microsoft's own description. The new features in 26H2 were already included in the monthly quality updates for 24H2 and 25H2, but in an inactive, dormant state. The upgrade itself is an enablement package, KB5121794, which Microsoft calls a small, quick-to-install "master switch" that activates those features. Installing it needs a single restart and much less downtime than a traditional full feature update, because it is not reinstalling Windows or downloading a multi-gigabyte operating system image.

That also explains what 26H2 is not. It is not a dramatic visual redesign, and most of its changes are features that had already been arriving through monthly updates during the year. Some features that were held back by temporary controls in 25H2 are enabled by default in 26H2. If you install it expecting a completely new-looking Windows, you may be underwhelmed. The real benefit is not cosmetic; it is the restored support clock, running to October 2028 for Home and Pro, and to October 2029 for Enterprise and Education.

Before you install, you need one prerequisite. Microsoft says you must already run version 24H2 or 25H2, and you must have the 22 September 2026 update, KB5124010, or a later cumulative update installed. In practice, Windows Update normally takes care of this for you, but if your PC has been offline or updates have been paused for a long time, install the latest cumulative update first and then look for the 26H2 offer.

Step by step: install Windows 11 26H2

Back up anything you cannot afford to lose before any feature update, even a small one. A full backup to an external drive or a cloud service is the safest option, and it is worth doing precisely because the update is usually uneventful; the one time it matters is the time you skipped it. Close unsaved work, and plug a laptop into power so it does not run out of battery mid-restart.

First, open Settings and select Windows Update. Turn on "Get the latest updates as soon as they're available" if it is not already on, because Microsoft names this setting as the way to be offered 26H2 sooner once your PC is eligible. Then select Check for updates and let Windows Update finish checking.

If "Windows 11, version 26H2 is available" appears, select Download and install. You can select "See what's in this update" first if you want to read Microsoft's description before committing. When the download and preparation finish, restart the PC when Windows asks. One restart completes the move to 26H2.

After the restart, verify the result instead of assuming it worked. Press Windows key and R, type winver, and press Enter again. It should now show version 26H2 and a build starting with 26300. Also open Settings, then Windows Update, and check that it reports you are up to date. If both checks agree, you are back on a supported version, and the November security updates will arrive as normal.

If you rely on specific hardware or software for work, take one extra precaution before installing: check Microsoft's Windows release health page for known issues with version 26H2. A safeguard hold, explained below, usually protects PCs with a known compatibility problem, but a quick look at the known-issues list is still sensible if your setup is unusual, such as specialised audio hardware, older peripherals or industry-specific software.

If 26H2 does not appear: do not force it

The most common question after a new Windows version ships is why it has not appeared yet, and the answer is usually unglamorous: Microsoft rolls feature updates out in stages, a controlled rollout, so eligible PCs are offered the update at different times. Turning on "Get the latest updates as soon as they're available" moves you earlier in that queue, but it does not guarantee an instant offer.

A second reason is a safeguard hold. If Microsoft has identified a known compatibility problem affecting your particular hardware or driver combination, it holds the update back for that configuration until the problem is addressed. That hold is a protection, not a bug, and working around it with unofficial downloads defeats its purpose. If 26H2 is not offered, check the Windows release health page for known issues, make sure the latest cumulative update is installed, and check again after a few days. Your PC will keep working in the meantime; the risk of staying on 24H2 for a short additional period while waiting for a clean offer is far smaller than the risk of forcing an incompatible update from an unofficial source.

What you should not do is download a so-called 26H2 ISO or enablement package from a random website, a video description or a file-sharing link. Microsoft delivers this update through Windows Update and its managed deployment channels, and unofficial installers are a classic route for malware disguised as a helpful fix. If a site promises to bypass a safeguard hold or to install 26H2 on a version that Microsoft says cannot take the enablement package, treat that as a warning sign, not a solution.

If weeks pass and 26H2 still does not appear, and your PC is a personal Home or Pro machine on 24H2, use Windows Update's Check for updates regularly, confirm you are not on a metered connection that pauses downloads, and confirm updates are not paused in Settings. For a managed work or school PC, ask your IT team rather than intervening yourself, because managed update policies can legitimately delay or redirect feature updates.

If something breaks after the upgrade

Most 26H2 upgrades from 24H2 or 25H2 finish with one restart and no drama, because the underlying system files are the same. If something does break, act promptly rather than living with it and hoping a later monthly update fixes it. First, check whether the problem is a driver or app that needs its own update, since feature updates sometimes expose an outdated driver rather than causing a new fault. Check the manufacturer's site for a current driver, and check Microsoft's known-issues page to see whether your symptom is already listed with a workaround.

Windows also keeps a recovery option after a feature update. In Settings, then System, then Recovery, you will find a Go back option for a limited window after upgrading, 10 days by default, which returns the PC to the previous version. That window is short by design, so do not spend it researching indefinitely; if a serious problem, such as a device you depend on no longer working, appears right after the upgrade, decide within the first few days whether to roll back, fix the driver, or wait for a documented fix. Note the date you upgraded, so the window does not quietly expire while you are still deciding.

If you roll back to 24H2 Home or Pro, remember what you are rolling back to: a version whose updates have ended. A rollback is a reasonable short-term step to restore a working PC, but it is not a long-term plan. Fix the underlying problem, whether that is a driver update or an app update, and move forward to a supported version again as soon as you can.

The support clocks at a glance

It is easy to lose track of which version ends when, so here are the dates from Microsoft's release information, for the versions most home users will meet.

Windows 11 version 24H2, Home, Pro, Pro Education and Pro for Workstations: updates ended 13 October 2026. The same version in Enterprise, Education and IoT Enterprise editions: updates until 12 October 2027.

Windows 11 version 25H2, Home, Pro, Pro Education and Pro for Workstations: updates until 12 October 2027. Enterprise and Education editions: updates until 10 October 2028.

Windows 11 version 26H2, Home, Pro, Pro Education and Pro for Workstations: updates until 10 October 2028. Enterprise and Education editions: updates until 9 October 2029.

The pattern is consistent: each version gets 24 months for Home and Pro and 36 months for Enterprise and Education. Once you are on 26H2, the next deadline to keep in mind is October 2028, not next month. That is the practical payoff of this upgrade: it buys roughly two years of monthly security updates in exchange for one restart.

Checklist: get back on a supported version

Check your version with winver or Settings, then System, then About, and note both the version and the edition.
If you are on 24H2 Home, Pro, Pro Education or Pro for Workstations, plan the upgrade to 26H2 now, before the 10 November security updates.
Back up files you cannot afford to lose, and plug a laptop into power before starting.
In Settings, then Windows Update, turn on "Get the latest updates as soon as they're available" and select Check for updates.
Install the latest cumulative update first if one is waiting, since 26H2 needs the 22 September 2026 update, KB5124010, or a later cumulative update.
When "Windows 11, version 26H2 is available" appears, select Download and install, then restart once when asked.
After the restart, run winver again and confirm version 26H2 and a build starting with 26300.
If 26H2 does not appear, check Microsoft's Windows release health page for known issues and safeguard holds, and check again later rather than forcing it from an unofficial download.
If you run 24H2 Enterprise or Education, or a managed work or school PC, stay on your organisation's schedule instead of forcing a personal upgrade.
If you run 23H2 or older, or Windows 10, use the full feature-update route for your version, not the 26H2 enablement package.

Bottom line

Windows 11 24H2 Home and Pro stopped receiving security updates on 13 October 2026, and the next monthly security release, on 10 November 2026, will not reach those PCs. The fix is free, small and quick for most affected users: check your version with winver, install Windows 11 version 26H2 through Settings and then Windows Update, restart once, and confirm the new version. That restores security updates until 10 October 2028 for Home and Pro. If 26H2 has not been offered yet, wait for the staged rollout or a safeguard hold to clear, and do not bypass it with an unofficial installer. Your PC has not stopped working, but its protection clock has, and one restart is a small price for two more years of it.
