Known issues in this update

Symptom Workaround For hosts managed by System Center Virtual Machine Manager (SCVMM), SCVMM cannot enumerate and manage logical switches deployed on the host after installing the update.
Additionally, if you do not follow the best practices, a stop error may occur in vfpext.sys on the hosts.

Run mofcomp on the following mof files on the affected host:

Scvmmswitchportsettings.mof

VMMDHCPSvr.mof

Follow the best practices while patching to avoid a stop error in vfpext.sys in an SDN v2 environment (NC managed hosts).
