  • Removes the history of previously used pictures from a user account profile.
  • Addresses an issue that displays the wrong language when you sign in to a console after you change the system locale.
  • Addresses an issue that causes the host process of Windows Remote Management (WinRM) to stop working when it formats messages from a PowerShell plugin.

  • Addresses an issue with screen rendering after opening games with certain hardware configurations.
  • Improves startup times for applications that have roaming settings when User Experience Virtualization (UE-V) is turned on.
  • Addresses an issue in which a principal in a trusted MIT realm fails to obtain a Kerberos service ticket from Active Directory domain controllers (DC). This occurs on devices that installed Windows Updates that contain CVE-2020-17049 protections and configured PerfromTicketSignature to 1 or higher. These updates were released between November 10, 2020 and December 8, 2020. Ticket acquisition also fails with the error, “KRB_GENERIC_ERROR”, if callers submit a PAC-less Ticket Granting Ticket (TGT) as an evidence ticket without providing the USER_NO_AUTH_DATA_REQUIRED flag.
  • Addresses high memory and CPU utilization in Microsoft Defender for Endpoint.
  • Enhances data loss prevention and insider risk management solution functionalities in Microsoft 365 endpoints.
  • Addresses an issue that displays an error when you attempt to open an untrusted webpage using Microsoft Edge or open an untrusted Microsoft Office document. The error is, “WDAG Report – Container: Error: 0x80070003, Ext error: 0x00000001”. This issue occurs after installing the .NET update KB4565627.
  • Addresses an issue that prevents wevtutil from parsing an XML file.
  • Addresses an issue that fails to report an error when the Elliptic Curve Digital Signature Algorithm (ECDSA) generates invalid keys of 163 bytes instead of 165 bytes.
  • Adds support for using the new Chromium-based Microsoft Edge as the assigned access single kiosk app. Now, you can also customize a breakout key sequence for single app kiosks. For more information, see Configure Microsoft Edge kiosk mode.
  • Addresses an issue with User Datagram Protocol (UDP) broadcast packets that are larger than the maximum transmission unit (MTU). Devices that receive these packets discard them because the checksum is not valid.
  • Addresses an issue in which the WinHTTP AutoProxy service does not comply with the value set for the maximum Time To Live (TTL) on the Proxy Auto-Configuration (PAC) file. This prevents the cached file from updating dynamically.
  • Displays the proper Envelope media type as a selectable output paper type for Universal Print queues.
  • Ends the display of a random paper size for a printer when it uses the Microsoft Internet Printing Protocol (IPP) Class Driver.
  • Enables Windows to retrieve updated printer capabilities to ensure that users have the proper set of selectable print options.

  • Adds a new dfslogkey as described below:
    • Keypath: HKEY_LOCAL_MACHINE/SOFTWARE/MICROSOFT/dfslog.
    • The RootShareAcquireSuccessEvent field has the following possible values:
      • Default value = 1; enables the log.
      • Value other than 1; disables the log.

If this key does not exist, it will be created automatically. To take effect, any change to
dfslog/RootShareAcquireSuccessEvent in the registry requires that you restart the DFSN service.

  • Updates the Open Mobile Alliance (OMA) Device Management (DM) sync protocol by adding a check-in reason for requests from the client to the server. The check-in reason will allow the mobile device management (MDM) service to make better decisions about sync sessions. With this change, the OMA-DM service must negotiate a protocol version of 4.0 with the Windows OMA-DM client.
  • Turns off token binding by default in Windows Internet (WinINet).
  • Addresses an issue with failover in an environment that only has IPv6 clusters. If the failover cluster has been running for more than 24 days, attempts to do a failover might not succeed or might be delayed.
