Windows 11 24H2 End of Support in October 2026

Originally published at https://tekmag.thsite.top/windows-11-24h2-end-of-support-in-october-2026/

Windows 11 24H2 Home and Pro reach end of updates on October 13, 2026. After that date, affected PCs stop receiving security patches and Microsoft support for the version, so most users should move to 25H2 through the KB5054156 enablement package. Enterprise and Education editions stay supported until October 12, 2027.

I verified the dates directly against Microsoft's lifecycle page for Windows 11 Home and Pro and cross-referenced them with BleepingComputer's September 17 report. The numbers hold up: Home/Pro 24H2 drops off on October 13, 2026, Enterprise/Education 24H2 runs until October 12, 2027, and the 25H2 upgrade is a small enablement package rather than a full OS reinstall.

This is the last security update batch for most consumer machines running 24H2, and the window to move is open now.

Key Takeaways

Windows 11 24H2 Home and Pro reach end of updates on October 13, 2026. No security patches and no support for the version after that date.
24H2 Enterprise and Education are supported until October 12, 2027, under Microsoft's 36-month commercial lifecycle.
The upgrade to 25H2 is an in-place enablement package (KB5054156), not a reinstall. Files, apps, and settings are preserved.
Windows 10's paid Extended Security Updates program is extended to October 12, 2027, but it applies to Windows 10 only. It does not cover Windows 11 24H2.

What Happens on October 13

On October 13, 2026, Windows 11 version 24H2 for Home and Pro stops receiving feature, quality, and security updates, per Microsoft's September 2026 servicing notes. Microsoft lists the date in Pacific Time, so the effective cutoff is late that evening. After it, your 24H2 machine keeps working. The desktop boots, apps run, files open. What changes is that new vulnerabilities found in the 24H2 version will no longer be fixed on that version, and there is no longer a support channel to call about them.

"The risk after October 13 is not a dead PC. It is an unpatched one."

The versions that follow keep a longer runway. According to Microsoft's Windows 11 release information page, 25H2 for Home and Pro is supported until October 12, 2027, 25H2 Enterprise and Education until October 10, 2028, and 26H1 Home/Pro until March 14, 2028. Enterprise and Education builds of 24H2 itself get a 36-month window ending October 12, 2027, as listed on the Enterprise and Education lifecycle page.

If you are a Windows 10 user hoping to just buy ESU and stay put, read on. That option exists, but it is not for 24H2.

Why It Matters

"An unpatched consumer OS is a known exploit target. Monthly patching is the cheapest insurance a PC can have."

End of support means the exact build you run stops getting fixes, while the vulnerabilities in it keep accumulating. Patch Tuesday stops touching 24H2 Home/Pro, and the attack surface on an old version only grows. For a laptop you keep in service for years, that is a compounding exposure, not a one-off.

The Windows 10 angle matters here too. Microsoft has extended the paid consumer Extended Security Updates program for Windows 10 to October 12, 2027, per the ESU page. "Windows 10 users have a bridge, a paid one running to October 2027. Windows 11 24H2 users have an Upgrade." The ESU program does not cover Windows 11 of any version, which is the part most articles get wrong. 24H2 Home/Pro has no equivalent extension, so the only path off 24H2 before it goes quiet is moving to a newer Windows 11 version.

For businesses, the 36-month Enterprise window is a planning tool, not a free pass. The same enablement package 25H2 works on your office laptops can be staged through pilot groups and rolled out by WSUS or Intune on your schedule, instead of hitting every desk at once. TechRepublic framed it the same way, with IT teams treating 25H2 as a testable, deployable update rather than an emergency. Teams that keep their hardware a little longer can pair that with things like extending an SSD's lifespan with one setting so the machine that carries 25H2 actually outlives its drive.

How to Upgrade to 25H2

Windows 11 24H2, 25H2, and 26H2 all share one servicing branch, OS build 26100. That shared branch is why the 24H2 to 25H2 step is delivered as the KB5054156 enablement package instead of a full reinstall. The package flips the feature set on an existing install. Your files, apps, and settings are kept, which is the same in-place model Windows has used for feature updates since 2019.

For Home and Pro users

You should get the upgrade automatically through Windows Update. To move deliberately, open Settings, then Windows Update, then Check for updates. The enablement package shows up like any other feature update. Pick a reboot time that suits you, or pause the installation if you need a few more days. If it does not appear, Microsoft lists 25H2 on the release health page, and you can download the package directly from the Microsoft Update Catalog. One prerequisite to note: the package assumes you are on 24H2 with cumulative update KB5064081 or later, so run Windows Update a couple of times first if you have not touched it in a while.

Before you reboot, it is worth sorting out how fast the machine actually is, since the enablement package can trigger a large background install. Our Windows 11 speed-up guide covers the ten tweaks that actually move performance, and a cleaner install is more pleasant to work on for the next year and a half.

For Enterprise and Education admins

Because your 24H2 machines are still supported until October 12, 2027, you have room to stage this. Validate KB5054156 on a pilot group, approve the 25H2 feature update in WSUS or deploy it through Intune, and track adoption with Endpoint Manager analytics. The manual route is to pull the .msu from the Microsoft Update Catalog and apply it with the standalone installer or DISM offline. The same KB5064081 prerequisite applies before the enablement package will attach.

Timeline for 26H2

26H2 is already moving. Microsoft shipped it to the Release Preview Channel on August 27, 2026, as build 26300.9278. General availability is expected around the October 13, 2026 patch Tuesday, or later that month, as Windows Central outlined. Because 26H2 rides the same shared servicing branch, it too will arrive as an enablement package for the machines already on it. The support runway for 26H2 Home and Pro lands around October 2028, a full two years of patches.

One number to keep straight: 26H1 is not an in-place update for your current PC. Microsoft scoped it for new devices shipping in early 2026 only. If you are planning which version your 24H2 machine will end up on, 25H2 and 26H2 are the choices. 26H1 will not appear in your update queue, which is the same detail BleepingComputer flagged in its report.

Conclusion

Microsoft is holding the line on a two-year consumer support window, and the result is that 24H2 Home and Pro go quiet in three weeks. The 36-month Enterprise runway and the October 2027 Windows 10 ESU extension both say the same thing: Microsoft is moving existing fleets forward, not keeping old versions alive. 26H2 in Release Preview confirms the cadence is now annual feature updates with enablement-package upgrades, which is far lighter to run than the old full reinstall era. My read: the practical move for a consumer machine is to trigger the 25H2 enablement package now and not chase 26H2 on day one. The upgrade takes minutes and buys a year and a half of patches, which is the whole point. If you found this useful, share it with anyone still on 24H2, or drop a comment with questions about moving a mixed fleet to 25H2.
