Applications that may exhibit this behavior use an IFRAME during non-interactive authentication requests and receive X-Frame Options set to DENY.

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

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.

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.

Devices that start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM) may fail to start with the error "Status: 0xc0000001, Info: A required device isn't connected or can't be accessed" after installing this update on a WDS server.

This issue is resolved in KB4512495.

Devices connected to a domain that is configured to use MIT Kerberos realms may not start up or may continue to restart after installation of this update. Devices that are domain controllers or domain members are both affected.

If you are not sure if your device is affected, contact your administrator. Advanced users can check if this registry key exists HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\MitRealms or for “Define interoperable Kerberos v5 realm settings” policy under Computer Configuration -> Policies -> Administrative Templates > System -> Kerberos.

This issue is resolved in KB4512517.

This issue is resolved in KB4512517.

Applications and scripts that call the NetQueryDisplayInformation API or the WinNT provider equivalent may fail to return results after the first page of data, often 50 or 100 entries. When requesting additional pages you may receive the error, “1359: an internal error occurred.”

This issue is resolved in KB4516044.
