Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

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).

After installing KB4467684, the cluster service may fail to start with the error “2245 (NERR_PasswordTooShort)” if the group policy “Minimum Password Length” is configured with greater than 14 characters. Set the domain default "Minimum Password Length" policy to less than or equal to 14 characters.
Microsoft is working on a resolution and will provide an update in an upcoming release. After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension. To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options:
Option 1:
Open an Administrator Command prompt and type the following:
Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No
Option 2:
Use the Windows Deployment Services UI.

Open Windows Deployment Services from Windows Administrative Tools.

Expand Servers and right-click a WDS server.

Open its properties and clear the Enable Variable Window Extension box on the TFTP tab.

Option 3:
Set the following registry value to 0:
“HKLM\System\CurrentControlSet\Services\WDSServer\Providers\WDSTFTP\EnableVariableWindowExtension”.
Restart the WDSServer service after disabling the Variable Window Extension.
Microsoft is working on a resolution and will provide an update in an upcoming release. Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege. Do one of the following:

Perform the operation from a process that has administrator privilege.

Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.
