Scans that use these servers will fail if the clients do not have a configured system proxy. If you must leverage a user proxy, you must configure the behavior by using the Windows Update policy **Allow user proxy to be used as a fallback if detection using system proxy fails**. To make sure that the highest levels of security, additionally leverage Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices. For more information, see [Changes to scans, improved security for Windows devices](<https://aka.ms/WSUS-scans-part2>). **Note** This change does not affect customers who use HTTP WSUS servers. * Addresses an issue in which a principal in a trusted Managed Identity for Application (MIT) realm does not obtain a Kerberos Service ticket from Active Directory domain controllers (DCs).

Ticket acquisition fails with **KRB_GENERIC_ERROR** if callers submit a PAC-less Ticket Granting Ticket (TGT) as an evidence ticket without providing the **USER_NO_AUTH_DATA_REQUIRED** flag. * Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Fundamentals, Windows Cryptography, Windows Virtualization, and Windows Hybrid Storage Services.
