Microsoft has fixed a known issue that broke Always On VPN connections for some Windows 11 users after they installed the September 2026 security updates. The company confirmed the resolution, according to a report from BleepingComputer.
The problem specifically affected the Always On VPN feature, which automatically establishes a VPN connection for users. After applying the September 2026 updates, some users found that their VPN connections failed or could not be established.
With this fix, Microsoft has addressed the underlying cause. Users who experienced the issue should now be able to use Always On VPN normally again. No further technical details were provided in the source.
