Windows 10/11 and L2TP Connections Failing

So I work for a POS company and many customers are calling in about their VPN connections failing recently.

Seems to be related to a recent KB update that has caused some issues with the Vendor ID not getting synced during the initial negotiations ?

Normally you should not just uninstall a security update but here are the relevant KB articles and how to remove each manually.

Windows 10: wusa /uninstall /kb:5009543
Windows 11: wusa /uninstall /kb:5009566

Just open a CMD shell as an admin or use powershell.

So has anybody run across this yet ?
