  • 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.

  • 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.

    • 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.

    ich habe das optionale Update mal installiert und wunderte mich schon mal , warum die Geschichte so lange dauert. Nach Neustart ploppte nun das NET-update auf und verlangt wieder nach Neustart.

    Interessantes Update-Verhalten von MS. Unabhängig davon klappt wohl auch nicht die Einstellung zu den Updates.
