Preview of Monthly Rollup

Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4056896 (released January 4, 2018) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

  • Addresses issue where every smart card logon to a Windows Terminal Server/Remote Desktop Server may result in a handle leak in the certprop service. Token leaks result in session leaks on computers that have installed MS16-111/KB3175024 and superseding fixes.

  • Addresses the following issues with the WinRM service:

    • A threading issue that may cause the WinRM service to crash under load. This is a client-side solution, so you must apply it to the affected computers(s) and the computers that communicate with the WinRM service.

    • A system performance issue that may cause logon to stop responding with the message, "Please wait for the Remote Desktop Configuration". This was caused by a deadlock in the WinRM service.

  • Addresses issue originally called out in KB4056896 where calling CoInitializeSecurity with the authentication parameter set to RPC_C_AUTHN_LEVEL_NONE resulted in the error STATUS_BAD_IMPERSONATION_LEVEL.

For more information about the resolved security vulnerabilities, see the Security Update Guide.
