Updates enforce SID checks, causing Windows login failures

🔒 Microsoft confirmed that Windows updates released on and after August 29, 2025 enforce additional SID checks that can break Kerberos and NTLM authentication on devices with duplicate Security Identifiers (SIDs). Affected systems — including Windows 11 24H2, Windows 11 25H2, and Windows Server 2025 — may experience failed Remote Desktop sessions, SEC_E_NO_CREDENTIALS event errors, and "access denied" messages. The fault commonly arises when images are duplicated without using Sysprep. Microsoft recommends rebuilding impacted machines with supported imaging procedures or obtaining a temporary Group Policy from Support as an interim measure.

A new driver is available via Windows Update and Microsoft recommends installing the latest security update; restarting the device may speed the offering.
