Improvements and fixes

This security update includes quality improvements. Key changes include:

• 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.
• Security updates to the Microsoft Scripting Engine, Windows App Platform and Frameworks, Windows Input and Composition, Windows Management, the Windows Cloud Infrastructure, Windows Fundamentals, Windows Authentication, the Windows Kernel, Windows Remote Desktop, and Windows Storage and Filesystems.
  If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
