According to Redmond, devices impacted by these Windows Hello authentication issues include those with the Dynamic Root of Trust for Measurement (DRTM) or System Guard Secure Launch features enabled before deploying the KB5055523 update. After installing this update and performing a Push button reset or Reset this PC from Settings > System > Recovery and selecting Keep my Files and Local install, some users might be unable to login to their Windows services using Windows Hello facial recognition or PIN," Microsoft explains. Earlier this week, Redmond also introduced a new Windows 11 24H2 safeguard hold for systems with SenseShield Technology's sprotect.sys driver (used by security or enterprise software) because of incompatibility issues that trigger blue or black screen of death (BSOD) errors. Other upgrade blocks prompted by incompatible software or hardware have also been applied to Windows devices with Dirac audio improvement software, integrated cameras, or the Easy Anti-Cheat and Safe Exam Browser apps. Microsoft says some Windows users might be unable to log into their accounts via Windows Hello after installing the April 2025 security updates. On Tuesday, Microsoft fixed another KB5055523 bug that caused authentication issues when Credential Guard was enabled on systems using the Kerberos PKINIT pre-auth security protocol.
