Windows 11 version 24H2 reached the end of its security-update life for Home and Pro editions on October 13, 2026. From that date, Microsoft no longer ships monthly security updates or optional non-security preview updates to PCs on those editions, and the company’s recommended route is a move to Windows 11 26H2, the 2026 Update. Machines that stay on 24H2 keep running, but any flaw found after the October patch cycle goes unrepaired.

The cutoff covers a specific slice of the Windows 11 population. It applies to the consumer editions, Home and Pro, rather than to every installation of the 24H2 release, because Microsoft sets lifecycle dates by edition. A family laptop that shipped with Home and a small-office desktop running Pro both fall on the unsupported side of the line, while managed business fleets running Enterprise or Education are on a separate and longer calendar. The label 24H2 refers to the second half of 2024, when that annual feature update shipped, and each such update carries its own servicing clock rather than inheriting the one before it.
The October 13 end date for Home and Pro
Sergiu Gatlan of BleepingComputer reported that Microsoft confirmed Windows 11 24H2 Home and Pro had reached end of support, noting that affected devices stop receiving the monthly security and preview updates. Microsoft’s own lifecycle table for Windows 11 Home and Pro lists 24H2 as starting October 1, 2024 and closing in mid-October 2026, a servicing window of two years. Gatlan’s report points readers to that documentation, where each edition’s start and end dates are published, so the cutoff can be checked for any specific installation rather than taken from news coverage alone. The October 2026 cumulative update was therefore the last security rollup that Home and Pro installations on 24H2 were offered.
26H2 and the enablement-package upgrade
Microsoft’s answer is 26H2, which reached general availability in September 2026 as an enablement package. That delivery method matters because an enablement package switches on features already staged in the installed operating system rather than replacing it wholesale, which is why the BleepingComputer report describes a single restart completing the process. Devices that have the setting labeled “Get the latest updates as soon as they’re available” turned on, and that meet the eligibility checks, are offered the upgrade automatically in phases, so some machines see it before others.
The lifecycle table lists 26H2 for Home and Pro as starting September 29, 2026 and running through October 10, 2028, which restarts the two-year clock that 24H2 has just exhausted. The staggered rollout means two identical PCs can receive the offer days or weeks apart, and the BleepingComputer report adds that eligible devices install it without any manual download.
Enterprise and Education keep 24H2 until October 12, 2027
The same release remains supported on business editions. According to the BleepingComputer account, Windows 11 24H2 Enterprise and Education stay under mainstream support until October 12, 2027, a full year past the Home and Pro cutoff, consistent with Microsoft’s separate lifecycle page for Windows 11 Enterprise and Education. Information technology teams that manage those editions therefore have a year to schedule the move, whereas household and small-business users on Home or Pro do not.
Microsoft’s wider message-center note on the same date also states that Windows 10 Enterprise LTSB 2016 reached the end of updates, and that the October 2026 security update is the last one available for those editions. The Windows message center entry is the place where Microsoft posts such lifecycle notices.
What running an unsupported build means
The practical risk of staying on an unpatched build grows with time. Vulnerabilities disclosed after the cutoff are fixed only for supported versions, and attackers routinely compare patches to find the flaws they fix, so a machine left behind becomes easier to target with each monthly cycle. BleepingComputer also relayed a Microsoft warning that devices on unsupported Windows versions will lose security updates after next year’s Windows Update certificate rotation, which would make the gap between supported and unsupported systems harder to bridge later. Microsoft’s guidance, as relayed in that report, ties continued protection to running a supported version, which for Home and Pro now means 26H2.
The same Microsoft announcements bundled several other lifecycle changes that Gatlan summarized. Microsoft extended its free Extended Security Updates program for Windows 10 home users to October 2027, a separate track for PCs that never made the move to Windows 11, and Windows Server 2022 reached the end of mainstream support, with extended support continuing until October 2031. In sequence, the notices show a pattern in which each Windows release gets a fixed servicing window and a cutoff date that arrives whether or not a given household has noticed it.
Anyone unsure which build a PC is running can check the version number in the Windows settings About page, then compare it against the lifecycle tables. Microsoft’s Windows lifecycle FAQ explains how the company applies edition-based end dates and what end of servicing means for updates, support and security fixes.
