Windows 11 24H2 users on Home and Pro have until October to move to a supported release before monthly security updates stop.
Microsoft is warning that Windows 11 version 24H2 Home and Pro editions will reach end of support on Oct. 13, 2026. After that date, affected PCs will no longer receive Microsoft’s monthly security and non-security updates, leaving users and IT teams responsible for moving eligible systems to a newer Windows release.
The deadline matters particularly for mixed business fleets because Enterprise and Education editions of 24H2 remain supported for another year, creating two different patch timelines for devices that may appear to be running the same Windows version.
Microsoft confirmed in its Windows message center that Windows 11 24H2 Home and Pro editions will stop receiving monthly security and non-security preview updates after Oct. 13. Windows 10 Enterprise LTSB 2016 reaches its own end-of-updates milestone on the same date.
The upgrade path to 25H2
First launched in October 2024, version 24H2 operates on Microsoft’s standard 24-month lifecycle for consumer and business desktop editions. To stay secure, Microsoft advises users to transition to Windows 11, version 25H2, which extends monthly support through Oct. 12, 2027.
For everyday consumers whose devices are unmanaged, the switch to version 25H2 will occur automatically via an enablement package, though users can still schedule reboots or temporarily pause installation. Eligible users can trigger the process manually under Settings > Windows Update by selecting Check for updates.
The retirement schedule also affects enterprise environments running Windows 10 Enterprise LTSB 2016, which reaches the end of its extended support on the same date.
For specialized, fixed-purpose environments running the retiring Windows 10 Enterprise LTSB 2016, Microsoft recommends migrating to Windows 11 Enterprise LTSC 2024 or purchasing paid Extended Security Updates (ESU) as a transitional bridge.
However, standard Windows 11 24H2 Home and Pro editions are not eligible for ESUs and must be updated directly to a supported feature release like 25H2 to continue receiving monthly updates.
Split lifecycles and enterprise fleet exposure
The Oct. 13, 2026 deadline underscores an operational risk for mixed corporate fleets: the widening support gap between consumer and enterprise editions.
While Windows 11 24H2 Home and Pro lose support this October, Windows 11 24H2 Enterprise and Education editions remain supported for an additional year, until Oct. 12, 2027, thanks to their 36-month lifecycle. In remote or hybrid workplaces where employees frequently connect using Pro edition workstations or unmanaged laptops, IT departments face a hidden security blind spot.
If endpoint inventories fail to cleanly separate Pro builds from Enterprise builds, unpatched systems will fall out of compliance. Once monthly patches cease, these endpoints will no longer receive fixes for newly disclosed vulnerabilities, increasing security and compliance exposure over time.
Preparing for the cutoff
To avoid disruption, administrators and users should take actionable steps before the October deadline:
- Audit endpoint inventories: Check internal build numbers and license editions to isolate 24H2 Pro workstations from Enterprise licenses.
- Test core software: Verify that virtual private networks (VPNs), endpoint detection and response (EDR) tools, and disk encryption remain fully compatible with version 25H2.
- Review update policies: Ensure that Windows Update for Business, Microsoft Intune, or custom deployment rings are not accidentally blocking the 25H2 feature release.
For most eligible Home and Pro users, the move to 25H2 should be straightforward. The bigger challenge is for organizations with mixed fleets, where identical-looking 24H2 installations can have different support deadlines depending on edition.
With Oct. 13 approaching, administrators should identify affected Pro endpoints now rather than discovering them after monthly security updates have already stopped.
