Improvements and fixes
This non-security update includes quality improvements. Key changes include:
- Addresses issues with Kerberos authentication related to the PerformTicketSignature registry subkey value in CVE-2020-17049, which was a part of the November 10, 2020 Windows update. The following issues might occur on writable and read-only domain controllers (DC):
. Kerberos service tickets and ticket-granting tickets (TGT) might not renew for non-Windows Kerberos clients when PerformTicketSignature is set to 1 (the default).
. Service for User (S4U) scenarios, such as scheduled tasks, clustering, and services for line-of-business applications, might fail for all clients when PerformTicketSignature is set to 0.
. S4UProxy delegation fails during ticket referral in cross-domain scenarios if DCs in intermediate domains are inconsistently updated and PerformTicketSignature is set to 1.










As with previous fall releases, Windows 10, version 20H2 is a scoped set of features for select performance improvements, enterprise features, and quality enhancements. As an H2-targeted release, 20H2 is serviced for 30 months from the release date for devices running Windows 10 Enterprise or Windows 10 Education editions.

This release automatically includes the new Chromium-based Microsoft Edge browser instead of the legacy version of Edge.

There also are several changes that help improve the security of devices that scan Windows Server Update Services (WSUS) for updates.

Starting with Windows 10, version 20H2, LCUs and SSUs have been combined into a single cumulative monthly update, available via Microsoft Catalog or Windows Server Update Services.
