This non-security update includes improvements and fixes that were a part of KB4520007 (released October 8, 2019) and also includes these new quality improvements as a preview of the next Monthly Rollup update:
- Updates time zone information for Norfolk Island, Australia.
- Updates time zone information for the Fiji Islands.
- Addresses an issue that prevents netdom.exe from displaying the new ticket-granting ticket (TGT) delegation bit for the display or query mode.
- Addresses an issue in security bulletin CVE-2019-1318 that may cause client or server computers that don’t support Extended Master Secret (EMS) RFC 7627 to have increased connection latency and CPU utilization. This issue occurs while performing full Transport Layer Security (TLS) handshakes from devices that don’t support EMS, especially on servers. EMS support has been available for all the supported versions of Windows since calendar year 2015 and is being incrementally enforced by the installation of the October 8, 2019 and later monthly updates.
