Windows 11 version 24H2, build 26100, is down to its final Patch Tuesday. Microsoft’s release-health table lists October 13, 2026 as the end of updates for the Home, Pro, Pro Education and Pro for Workstations editions, two years after the version reached the public on October 1, 2024.
The cutoff is narrower than it first sounds. Enterprise and Education editions of the same 24H2 release keep receiving updates into October 2027, so the October 13 date applies to the editions most households and small offices run. Microsoft’s pages also disagree with each other by a day on the exact cutoff, a wrinkle covered below, but both point to the same October Patch Tuesday as the final security release for Home and Pro on this version.
The name 24H2 encodes the second half of 2024. Each Home and Pro version is serviced for 24 months, which is why a version released on October 1, 2024 reaches its end of updates in the second week of October 2026, a fixed two-year distance that was visible from the day the version shipped.
The October 13 entry for 24H2 Home and Pro
The date appears on Microsoft’s 2026 end-of-support list under end of servicing, as “Windows 11 Home and Pro, Version 24H2,” and the same list carries the Office 2021 retirement on that day. That overlap is why the Windows entry reads as a second item on a crowded date rather than a standalone event; the list also names Windows Server 2012 and 2012 R2 Extended Security Update Year 3, several LTSC editions and Dynamics 365 Business Central on October 13.
October 13 is also the second Tuesday of the month, which is when Microsoft’s Windows 11 release-health page says monthly security updates ship. The practical reading is that the October 2026 security release is the last one 24H2 Home and Pro will receive. The page’s latest listed build for the version is 26100.9550, delivered in the September 2026 update, KB5124010.
For Pro for Workstations and Pro Education, the release-health table lists the same end date as Home and Pro, and the lifecycle FAQ treats all of those as the 24-month group. Enterprise, Education and IoT Enterprise are the 36-month group, which is the reason an organization running 24H2 on managed PCs has until October 2027 while a family laptop on the same build does not.
Servicing lengths by edition
Microsoft’s Windows lifecycle FAQ sets the rule: Pro, Home and SE editions are serviced for 24 months from release, while Enterprise, Education and IoT Enterprise get 36. Version 24H2 follows that formula exactly, with a release on October 1, 2024, a Home and Pro end in October 2026 and an Enterprise and Education end a year later, in October 2027. Windows 11 SE editions are covered by the same 24-month group, though the lifecycle page notes the SE edition ended its support with version 24H2.
The two lifecycle pages do not quite agree on the clock. The Home and Pro lifecycle page lists 24H2 as ending at 6:59:59 a.m. Pacific on October 14, 2026, whereas the release-health table shows 2026-10-13. For the Enterprise and Education line, release health shows October 12, 2027 and the Enterprise and Education lifecycle page shows October 13, 2027. Both pairs differ by a single day.
Home gets one extra note: it cannot defer feature updates.
25H2, 26H1 and 26H2 as the landing versions
The release-health table lists three newer versions. Version 25H2 became available on September 30, 2025 and runs through October 12, 2027 for Home and Pro, and through October 10, 2028 for Enterprise and Education. Version 26H2 arrived on September 29, 2026, only days ago, with Home and Pro servicing to October 10, 2028 and Enterprise and Education servicing to October 9, 2029. Counting from the release dates, 25H2 offers roughly a year of Home and Pro servicing beyond 24H2, and 26H2 offers about two years.
Version 26H1, available since February 10, 2026, is a different case. Microsoft’s table notes that it is not offered as an in-place update and is scoped for new devices only, so a machine already on 24H2 cannot take it as an upgrade path. For those machines the realistic targets are 25H2 and 26H2, both of which are listed with Home and Pro servicing that runs past the 24H2 cutoff by a year or more.
The same lifecycle FAQ lays out what staying supported takes: Windows kept on a version that is still inside its servicing window, monthly quality updates installed, and each feature update adopted before the current version reaches end of servicing. A 24H2 Home or Pro machine that has not moved by October 13 falls outside the first of those conditions, and the monthly updates it can install stop applying to it after that release.
On the release-health page, the numbers show how closely the supported versions track each other: 24H2 and 25H2 both list the September 2026 update, KB5124010, at builds 26100.9550 and 26200.9550. Version 26H1, which has its own update, KB5124006, at build 28000.3086, sits on its own servicing line, and its Home and Pro servicing is listed through March 14, 2028.
