Microsoft Sunsets Windows 11 24H2 on Home, Pro

En bref

• Microsoft ended support for Windows 11 24H2 on Home and Pro.
• Monthly security patches and preview updates have stopped.
• Devices running that build are now unpatched.
• No CVE prompted the change; severity is medium.
• Admins should plan upgrades to a supported release.

Microsoft has declared that Windows 11 version 24H2 has reached the end of its support lifecycle for the Home and Pro SKUs. As of today, the company no longer provides monthly updates, including security fixes, and has also ceased preview updates. This is a scheduled lifecycle milestone, not a reaction to a specific vulnerability.

The impact falls on any device running Windows 11 24H2 on Home or Pro. That covers consumer PCs, small business workstations, and any other machine on those SKUs. Enterprise and Education editions are not mentioned in this announcement, so their support status may differ. IT admins should verify the exact build and edition on each endpoint.

Why this matters: without security patches, these systems become increasingly exposed to new threats. Even though no CVE is tied to this event, the absence of updates means future vulnerabilities will go unfixed. Compliance requirements often mandate a supported OS, so organizations may face audit issues. The severity is medium because there is no immediate exploit, but the risk grows over time.

Context: Microsoft typically provides 24 months of support for Windows 11 Home and Pro releases. The 24H2 version is relatively recent, so this end-of-support may catch some users off guard. It could reflect a policy change or an accelerated lifecycle. Regardless, the practical effect is that patching stops now.

What to watch: Admins should monitor Microsoft's lifecycle documentation for any clarification or extension. Plan to migrate affected devices to a newer, supported Windows 11 release. Confirm that update mechanisms are working on remaining systems. Watch for any guidance from Microsoft about upgrade paths or exceptions.

À faire maintenant

1. Inventory all endpoints to identify devices running Windows 11 24H2 on Home or Pro.
2. Verify the edition and build number using system information tools.
3. Prioritize upgrading affected devices to a supported Windows 11 version.
4. Enable automatic updates and confirm they are receiving patches.
5. Document any exceptions and monitor Microsoft's lifecycle page for changes.
6. Communicate the end-of-support deadline to users and stakeholders.
7. Consider isolating unpatched systems if they cannot be upgraded immediately.
