This non-security update includes quality improvements. Key changes include:
Addresses a known issue that might cause IP Security (IPSEC) connections that contain a Vendor ID to fail. VPN connections using Layer 2 Tunneling Protocol (L2TP) or IP security Internet Key Exchange (IPSEC IKE) might also be affected.
Addresses a known issue that might cause Windows Servers to restart unexpectedly after installing the January 11, 2022 update on domain controllers (DCs).
Addresses an issue that prevents Active Directory (AD) attributes from being written properly during a Lightweight Directory Access Protocol (LDAP) modify operation when you make multiple attribute changes.
Addresses an issue that might prevent removable media that is formatted using the Resilient File System (ReFS) from mounting or might cause the removable media to mount in the RAW file format. This issue occurs after installing the January 11, 2022 Windows update.

The VPN fix is only applicable to people running L2TP/IPSEC on their PCs and that are using Windows 10 20H2. It doesn't effect VPNs running a router.
