    Issues in this Windows 10Possible Workaround
    SCVMM can not list and manage logical switches on the host after the update is installed for hosts managed by System Center's Virtual Machine Manager (SCVMM).

    In addition, a stop error can occur on the vfpext.syson hosts if you do not follow the best practices.
    1. Run mofcomp on the affected host in the following mof records:
      • VMMDHCPSvr.mof
      • Scvmmswitchportsettings.mof
    2. To prevent a stop error in vfpext.sys in an SDN v2 setting (NC managed hosts), follow the best practices while patching.


    After KB4467684 is installed, if group policy "Minimum Password Length" is set to be larger than 14, the cluster service may fail to begin with the "2245 (NERR PasswordTooShort)" error.
    Set a "Minimum Password Length" domain default policy to 14 characters or less.
    Microsoft works on a resolution and will release an update for the next release.
    The errors of "STATUS BAD IMPERSONATION LEVEL (0xC00000A5)" may result in activities, including rename, performed on files or folders of the Cluster Shared Volume (CSV). This happens in a system that has no administrator privilege when you operate on a CSV owner node.
    Do one of the following:
    • Run a process that has the privilege of the administrator.
    • Perform the process from a node not owned by CSV.
    Microsoft is working on an update resolution in the forthcoming release.
