  • Addresses an issue that prevents Microsoft Office updates from downloading from the Microsoft Store. 
  • Updates time zone information for Buenos Aires, Argentina.

  • Addresses an issue with the Group Policy, "Turn off app notifications on the lock screen".
  • Addresses an issue that may prevent users from signing in and cause account lockouts when using the App-V client to start applications. The issue occurs because Kerberos authentication fails when trying to get user information from the domain name server (DNS). Modify the following registry key:

    • Setting: UseDcForGetUserInfo
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Shared\
    • Type: REG_DWORD
    • Value: Setting the following DWORD to nonzero will enable the solution.

  • Addresses an issue that prevents the authentication credentials dialog from appearing when an enterprise web server attempts to connect to the Internet. 
  • Addresses an issue that causes a client or server to restart when using a smart card to log in with User Name Hints to an Azure Active Directory (AAD) joined machine using Remote Desktop Services.
  • Addresses an issue in which multiple device entries exist for a single, hybrid domain joined device. 
  • Addresses an issue that removes the ALLOWCLSIDS policy from the policy XML file when you run the Add-SignerRule for Windows Defender Application Control. 
  • Addresses an issue that prevents a virtual smart card from starting when running in conjunction with Citrix 7.15.2000 Workstation VDA software. 
  • Addresses an issue that prevents a user from authenticating and causes Windows Account Manager (WAM) to fail when using a Trusted Platform Module (TPM). 
  • Addresses an issue that causes certificate renewal to fail when using CERT_RENEWAL_PROP_ID with the ICertPropertyRenewal interface. 
  • Adds a new Group Policy setting called “Enable Windows to soft-disconnect a computer from a network”. This determines how Windows will disconnect a computer from a network when it determines that the computer should no longer be connected to the network.

    • If enabled, Windows will soft-disconnect (disconnection is not immediate or abrupt) a computer from a network.
    • If disabled, Windows disconnects a computer from a network immediately.
    • If not configured, the default behavior is soft-disconnect. For more information about soft-disconnect, see Understanding and configuring Windows Connection Manager.

Path: Computer Configuration\Policies\Administrative Templates\Network\Windows Connection Manager

  • Addresses an issue that may cause the error, “Stop 0x133” in NTFS.sys
  • Addresses an issue that causes Windows to reuse an expired Dynamic Host Configuration Protocol (DHCP) lease if the lease expired while the OS was shutdown.
  • Addresses an issue that may cause the Virtual Machine Management Service (VMMS) to stop working. This issue occurs when executing a Live Migration using a Measure-VM cmdlet or any metric Windows Management Instrumentation (WMI) query.

  • Addresses an issue in which the graphics device interface (GDI) DeleteObject() may cause the calling process to stop working when both of the following conditions are true:

    • The calling process is a WOW64 process that handles memory addresses larger than 2 GB.
    • The DeleteObject() is called with a device context that is compatible with a printer device context.
  • Provides seamless integration with Microsoft Cloud App Security (MCAS) to discover cloud app usage inside and outside the corporate network for Windows Defender Advanced Threat Protection (ATP) customers.
  • Enhances automated investigation and remediation, including memory forensics, for Windows Defender ATP customers.
  • Addresses an issue that prevents the “Turn off app notifications on the lock screen" policy from working. The path is "Computer Configuration\Administrative Templates\System\Logo".
  • Addresses minor issues with unknown options (unknown OPT) in the Extension Mechanisms for DNS (EDNS) for the Windows DNS Server role.

  • Addresses an issue to meet GB18030 certificate requirements.

  • Addresses an issue that prevents date parsers from converting future and past dates (Gregorian and Japanese) in compound documents (formerly OLE) to a relevant Japanese Era date. For more information, see KB4469068.

  • Addresses an issue that causes slow screen refresh rates when an application creates and destroys many child windows.

  • Addresses an issue that causes Wdiwifi.SYS to stop working with the error “7E (0xc0000005)”. This issue occurs when a client device is roaming between wireless access points (WAP) that have the same BSSIDs on the 2.4 Ghz and 5 Ghz bands.

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.

Any compound document (OLE) server application that places embedded objects into the Windows Metafile (WMF) using the PatBlt API may display embedded objects incorrectly.

For example, if you paste a Microsoft Excel worksheet object into a Microsoft Word document, the cells may render with a different background color.
This issue is resolved in KB4493464.
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.
