Key points

• Microsoft resolved a known issue affecting Always On VPN on Windows 11.
• The problem caused VPN connection failures and connectivity disruptions.
• No CVE was assigned; this was an operational bug, not a security flaw.
• IT admins should ensure devices are updated and test VPN connectivity.

Microsoft has addressed a defect that interfered with Always On VPN functionality on Windows 11. The issue led to failed connections and disrupted network access for affected devices. The fix was released in September 2026, according to the company.

Organizations and users who depend on Always On VPN for remote access were impacted, particularly in enterprise and education environments. Windows 11 devices were the only ones affected by this specific problem.

Always On VPN is critical for secure remote connectivity, so disruptions can halt productivity and block access to internal resources. Although no CVE was assigned—meaning this was not a security vulnerability—the operational impact was still significant for many IT teams.

Microsoft resolved the known issue, but administrators should verify that updates are applied and monitor for any residual problems. Checking VPN configurations and event logs can help confirm full restoration. Watch for further reports of connectivity issues as devices receive the patch.

What to do now

1. Deploy the latest Windows 11 cumulative updates to all affected devices.
2. Verify that Always On VPN profiles are correctly configured and applied.
3. Test VPN connectivity from a sample of Windows 11 devices after updating.
4. Review VPN and system event logs for any remaining errors or warnings.
5. If issues persist, open a support case with Microsoft and reference the known issue.
6. Consider temporary workarounds for critical remote workers until updates are fully deployed.
7. Document the resolution and update internal knowledge base for future reference.
