Improvements and fixes
This non-security update includes quality improvements. Key changes include:
- Addresses an issue that might cause domain controllers (DC) to register a lowercase and a mixed or all uppercase Domain Name System (DNS) service (SRV) record in the _MSDCS.<forest root domain> DNS zone. This occurs when DC computer names contain one or more uppercase characters.
- Addresses an issue that prevents machines that have enabled Credential Guard from joining a domain. The error message is "The server's clock is not synchronized with the primary domain controller's clock."
- Addresses an issue with running an application in RemoteApp that might cause the application window to flicker and DWM.exe might stop working on the session host.
- Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
- Addresses an issue that prevents Microsoft User Experience Virtualization (UE-V) settings from roaming to enable the signature files that are used for new messages, forwarded messages, and replies.
- Addresses an issue with high CPU usage on Active Directory Federation Services (AD FS) servers that occurs when the backgroundCacheRefreshEnabled feature is enabled.
- Addresses an issue that breaks the association among the Get-Iscsisession, Get-Iscsiconnection, and Get-Disk PowerShell commandlets when a cluster is created. This causes applications and scripts that rely on this association to fail.
- Addresses an issue that prevents certain apps from installing if they are published using a Group Policy Object.
If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
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.

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.
