Microsoft warns September Windows updates may break Always On VPN connections

Microsoft has issued a technical advisory warning users that the September security updates may cause connectivity issues with Always On VPN across some Windows 11 systems.

According to reports from BleepingComputer, the glitch affects the reliability of corporate remote access networks, causing unexpected disconnections for users relying on this specific security feature.

While the issue does not impact every single device, systems exhibiting this behavior struggle to maintain a stable encrypted connection after installing the latest patches.

For IT administrators and network engineers, this situation highlights the ongoing challenge of balancing crucial security updates with network stability in enterprise environments.

Microsoft is expected to provide further guidance or a permanent fix to resolve the VPN disruption and restore normal network operations for affected users.
