This non-security update includes improvements and fixes that were a part of KB4525243 (released November 12, 2019) and also includes these new quality improvements as a preview of the next Monthly Rollup update:
- Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
- Addresses an issue in which netdom.exe fails to correctly identify trust relationships when an unconstrained delegation is explicitly enabled by adding bitmask 0x800 to the trust object. The bitmask setting is required because of security changes to the default behavior of unconstrained delegations in Windows updates released on or after July 8, 2019. For more information, see KB4490425 and the article, 6.1.6.7.9 trustAttributes.
