Microsoft has announced that support for Windows 11 Home and Pro editions, version 24H2, will officially cease on October 13, 2026. This announcement serves as a 60-day notice for users to upgrade their systems to continue receiving security updates.
Impact of End of Support
Post the October 2026 deadline, devices running Windows 11 24H2 will no longer benefit from Microsoft’s monthly security patches or other updates. This could leave them susceptible to new vulnerabilities and cyber threats. The cessation of support affects Windows 11 Home, Pro, Pro Education, and Pro for Workstations versions using this update.
Initially released on October 1, 2024, Windows 11 24H2 provided a 24-month support window. This timeframe is crucial for cybersecurity teams, as missing updates can lead to increased risks, including remote code execution and security bypasses.
Recommendations for Users
Microsoft advises that users of Windows 11 24H2 Home and Pro editions transition to version 25H2. This newer version will remain supported until October 12, 2027, offering an additional year of critical updates. Released on September 30, 2025, Windows 11 25H2 is already available for upgrade.
It’s essential for IT departments to differentiate between the Home/Pro and Enterprise/Education editions. The latter retains support until October 12, 2027, offering a 36-month service period, which requires careful inventory checks and upgrade planning.
Preparing for the Transition
Identifying devices running Windows 11 24H2 is crucial. This can be done through system settings, endpoint management tools, or inventory systems. For the smoothest transition, organizations should test application compatibility, driver support, and ensure update policies do not block the upgrade to 25H2.
Microsoft’s guidance also highlights the upcoming end of extended support for Windows 10 Enterprise LTSB 2016 on the same date, October 13, 2026. Organizations are encouraged to consider migration to Windows 11 Enterprise LTSC 2024 to maintain support.
With the deadline approaching, it’s vital for organizations to act promptly to maintain security integrity. Completing upgrades before support ends will help mitigate risks associated with unpatched systems.
