KB5009543 and KB5009566 updates are breaking VPN connections in Windows
Updates for Windows are supposed to fix problems, boost security and add new features, but all too often they cause problems of their own. This month's Patch Tuesday updates for Windows 10 and Windows 11 are no different in this regard.
Earlier this week, Microsoft released KB5009543 for Windows 10 and KB5009566 for Windows 11. Users who have installed either of these updates are reporting issues with L2TP VPN connections.
