GoKawiilMicrosoft admits October patch did not fix Always On VPN bug
Microsoft told IT admins it wrongly marked an Always On VPN connection bug as resolved in October 2026 Windows 11 cumulative updates, reverting the status to 'Mitigated.' The bug, first acknowledged in September, can leave VPN connections stuck or failing with a 'port already in use' error on Windows 11 24H2 systems using automatic protocol selection.
GoKawiil's interpretation of the reporting above, not reported fact.
Always On VPN is widely used by enterprises for secure remote access, so a persistent connection bug could disrupt corporate network access for domain-joined and Entra ID-joined devices. Microsoft's mistaken resolution status suggests gaps in its patch verification process, which could erode admin trust in future update status reports.
- Microsoft reverted the bug's status from 'Resolved' to 'Mitigated' after October updates failed to fix it.
- A permanent fix is promised in a future update; a manual workaround using fixed VPN protocols is available now.
- The bug affects Windows 11 24H2 and later systems using automatic protocol selection for Always On VPN.
