Microsoft ends support for Windows 11 24H2 Home and Pro editions

Key Takeaways

• Microsoft is ending support for Windows 11 version 24H2 Home and Pro editions.
• Affected devices will stop receiving security updates on October 13, 2026.
• This deadline does not apply to Enterprise and Education editions of Windows 11 24H2, which have a longer support lifecycle.
• Organizations must upgrade to Windows 11 version 25H2 or later to maintain security patch coverage.

Microsoft Sunsets Windows 11 24H2 Home and Pro Editions

Microsoft has issued a critical 60-day notification, reminding users that Windows 11 Home and Pro editions, specifically version 24H2, will cease to receive updates as of October 13, 2026. After this date, systems running these versions will no longer benefit from Microsoft’s routine monthly security updates or non-security preview releases, leaving them increasingly vulnerable to emerging threats and malware.

The impending deadline impacts all deployments of Windows 11 Home, Pro, Pro Education, and Pro for Workstations that are currently running version 24H2. This particular feature update was initially rolled out by Microsoft on October 1, 2024, granting consumer and business-oriented editions the standard 24-month servicing window in line with the Windows servicing model. For cybersecurity professionals, this end-of-support date signifies a crucial operational and risk management milestone.

Regular cumulative updates are vital as they deliver patches for vulnerabilities that could otherwise be exploited for severe attacks, including remote code execution, privilege escalation, information disclosure, security feature bypasses, and denial-of-service incidents. While unsupported systems can continue to function, they will lack protection against newly identified threats. Microsoft strongly advises that eligible Windows 11 24H2 Home and Pro devices transition to Windows 11 version 25H2.

Understanding the Upgrade Path

The newer Windows 11 25H2 release offers an extended support period for these editions, continuing until October 12, 2027, thereby providing an additional year of essential security and quality updates. According to Microsoft’s release information, Windows 11 25H2 has been generally available since September 30, 2025.

It is crucial for organizations to differentiate this particular deadline from the lifecycle status of Windows 11 Enterprise and Education editions. Windows 11 24H2 Enterprise and Education devices benefit from a longer support window, extending until October 12, 2027, reflecting the 36-month servicing period allocated to these specific editions. This distinction necessitates accurate device inventory data for IT teams to effectively prioritize and plan their upgrade strategies.

Identifying and Migrating Affected Systems

Administrators can identify endpoints requiring attention by checking the Windows version and OS build via system settings, endpoint management platforms, or dedicated inventory tools. Windows 11 24H2 is associated with the 26100 build family, while Windows 11 25H2 corresponds to the 26200 build family. Asset records must also accurately reflect the edition type, as a 24H2 Enterprise device is not subject to the same October 2026 deadline as a 24H2 Pro workstation.

A comprehensive upgrade program should encompass compatibility testing for all critical business applications, device drivers, endpoint detection and response (EDR) agents, VPN clients, disk-encryption solutions, and any internally developed software. Security teams must also verify that existing update rings, Windows Update for Business policies, or Intune deployment configurations do not inadvertently impede the installation of the 25H2 feature update.

Microsoft’s reminder also extends to Windows 10 Enterprise LTSB 2016, which will reach its end of extended support on October 13, 2026. The company advises migrating these systems to the latest Long-Term Servicing Channel release, Windows 11 Enterprise LTSC 2024. While Extended Security Updates (ESU) may offer a temporary reprieve for organizations needing more time, this should be considered a short-term risk mitigation measure rather than a permanent alternative to migration.

What You Should Do

• Identify Affected Devices: Conduct a comprehensive audit to pinpoint all Windows 11 24H2 Home and Pro editions within your environment.
• Plan Your Upgrade: Develop and execute an upgrade plan to migrate all identified devices to Windows 11 version 25H2 or a later supported version before October 13, 2026.
• Test Compatibility: Prioritize thorough compatibility testing for all critical applications and hardware with the new Windows version.
• Review Update Policies: Ensure that your update management tools (e.g., Windows Update for Business, Intune) are configured to allow and deploy the 25H2 feature update.
• Consider Windows 10 LTSB Migration: For Windows 10 Enterprise LTSB 2016 users, plan migration to Windows 11 Enterprise LTSC 2024.
• Avoid Unsupported Systems: Treat any system remaining on an unsupported Windows version as a high-risk asset requiring immediate attention to prevent exploitation by threat actors.
