Windows 11 23H2 End of Support: What Enterprise and Education PCs Must Do Now

Windows 11 23H2 end of support for Enterprise and Education editions is here: Microsoft lists 10 November 2026 as the last day of updates for these editions, so this month’s security update is the final one. After that, PCs on 23H2 keep working but get no more security fixes. Move them to Windows 11 25H2 or 26H2 now. Because 23H2 can’t use the small enablement package, this is a full feature update that needs planning.

Quick summary

Who is affected	Windows 11, version 23H2: Enterprise, Education, IoT Enterprise and Enterprise multi-session
End of updates	10 November 2026 (Microsoft’s lifecycle page lists the end as 11 November, 6:59 AM Pacific Time)
Home and Pro on 23H2	Already past end of updates
Latest 23H2 build before November	22631.7654 (KB5134130, 26 October 2026)
Best upgrade target	Windows 11 26H2 (supported until 9 October 2029 on Enterprise/Education)
Upgrade type from 23H2	Full feature update (the enablement package works only from 24H2 and 25H2)

What Windows 11 23H2 end of support means

It means Microsoft stops shipping monthly security and quality updates for 23H2. Your PCs will still start, run apps and connect to the internet, but any Windows flaw discovered after November 2026 will stay open on them.

Windows 11 gets one feature update a year. Home and Pro editions get 24 months of updates for each version, while Enterprise and Education editions get 36 months. Version 23H2 arrived on 31 October 2023, so its 36 months on Enterprise and Education run out this month. Home and Pro PCs on 23H2 already reached end of updates earlier.

For businesses, an unpatched OS is a compliance problem as well as a security one. Many audits, cyber insurance policies and client contracts expect supported, patched operating systems on every endpoint.

Which Windows 11 version should you move to?

For most organisations, the answer is 26H2, because it gives the longest runway. Here are the dates from Microsoft’s release information page for Enterprise and Education editions.

Version	Released	Enterprise/Education updates end	Home/Pro updates end
23H2	31 Oct 2023	10 Nov 2026	Ended
24H2	1 Oct 2024	12 Oct 2027	Ended
25H2	30 Sep 2025	10 Oct 2028	12 Oct 2027
26H2	29 Sep 2026	9 Oct 2029	10 Oct 2028

Moving to 24H2 is not a good idea: it ends in less than a year, and you would face the same exercise again in 2027. Choose 25H2 only if your apps have been tested on it and not yet on 26H2. Microsoft also lists a 26H1 version, but it is meant for certain new devices and is not offered as an update to existing PCs.

Why 23H2 needs a full feature update

Microsoft says 26H2 reaches eligible PCs through a small enablement package, but only from versions 24H2 and 25H2, which share a common servicing branch with 26H2. Version 23H2 sits on an older branch, so it has to install the complete new version of Windows.

In practice, a full feature update means a much bigger download, a longer install with several restarts, and more chance of driver or app conflicts. Plan a pilot group first instead of pushing it to every PC in one night. Our Windows 11 26H2 upgrade guide covers the simpler enablement-package route for PCs that are already on 24H2 or 25H2.

How to upgrade 23H2 PCs: a 6-step plan

Use this checklist for an office or school network. Small offices with a few PCs can do steps 1, 2 and 5 by hand.

1. Find every 23H2 PC. On each PC, press Windows + R, type winver and press Enter, or open Settings > System > About. Version 23H2 shows as build 22631. In Intune or Configuration Manager, filter devices by OS build 22631.
2. Install the November 2026 update first. It is the last security update for 23H2, so it keeps PCs protected while you upgrade.
3. Test your key apps on 26H2. Upgrade a small pilot group with your accounting, ERP, VPN, antivirus and printing software, and check they work.
4. Back up user data. A feature update keeps files and apps, but a backup of desktops, documents and local databases protects you if an install fails.
5. Deploy the feature update. Use a feature update policy in Intune or Windows Update for Business, WSUS or Configuration Manager, or install from Microsoft’s official Windows 11 media for stand-alone PCs.
6. Verify and clean up. After a week, re-run your device report and follow up on any PC still showing build 22631.

If you don’t have an IT team for this kind of rollout, a managed IT services partner can plan the pilot, upgrades and reporting for you.

What’s new for businesses in Windows 11 26H2

Upgrading from 23H2 brings three years of features at once. Microsoft’s 26H2 notes for IT pros list these among the changes:

• Administrator protection, which can be switched on through Intune or Group Policy (off by default).
• Built-in Sysmon for detailed system event logging (off by default).
• Point-in-time restore and quick machine recovery to get broken PCs working faster.
• Policy-based removal of preinstalled Microsoft apps through Group Policy.
• Fewer restarts, as eligible updates install together with the monthly security update when possible.

Microsoft also notes that WMIC is no longer available as a Feature on Demand on 24H2 and later, so check any old scripts that call it before you upgrade. If you run into problems after updating, our Windows 11 problems and fixes guide is a good place to start.

Windows 11 23H2 end of support for Enterprise and Education is this month, so install the final November update and start moving PCs to 26H2.
