February 22, 2018—KB4075213 (Preview of Monthly Rollup)

Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4074593 (released February 13, 2018) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

• Updates time zone information.

• Addresses issue that causes services.exe to stop working after applying the "Obtain an impersonation token for another user in the same session” privilege to Windows Server 2012 R2 computers. These computers then enter a restart loop. The system may report the SceCli event ID 1202 with error 0x4b8. It may also report the Application Error event ID 1000 with the faulting module name scesrv.dll and the exception code 0xc0000409. This privilege was first introduced in Windows Server 2016.

• Addresses issue where the SMB Redirector may stop responding indefinitely when there is a large number of simultaneous loopback operations.
