Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release).

For more details about Microsoft’s plans, see Update on Adobe Flash Player End of Support.

Improvements and fixes

This security update includes improvements and fixes that were a part of update KB4601384 (released February 9, 2021) and addresses the following issues:
  • Addresses an issue in which a non-native device that is in the same realm does not receive a Kerberos Service ticket from Active Directory DCs. This issue occurs even though Windows Updates are installed that contain CVE-2020-17049 protections released between November 10 and December 8, 2020 and configured PerfromTicketSignature to 1 or larger. Ticket acquisition fails with KRB_GENERIC_ERROR if callers submit a PAC-less Ticket Granting Ticket (TGT) as an evidence ticket without the USER_NO_AUTH_DATA_REQUIRED flag being set for the user in User Account Controls.
  • Addresses an elevation of privilege security vulnerability documented in CVE-2021-1640 related to print jobs submitted to “FILE:” ports. After installing Windows updates from March 9, 2021 and later, print jobs that are in a pending state before restarting the print spooler service or restarting the OS will remain in an error state. Manually delete the affected print jobs and resubmit them to the print queue when the print spooler service is online.
  • Security updates to Windows Fundamentals, Windows Shell, Windows UAC, Windows Hybrid Cloud Networking, Windows Media, and Windows Graphics.
For more information about the resolved security vulnerabilities, please refer to the new Security Update Guide website.
