  • Addresses an issue that causes the Windows Hello for Business Hybrid Key Trust deployment sign-in to fail if Windows 2019 Server domain controllers (DC) are used for authentication. The error is, “That option is temporarily unavailable. For now, please use a different method to sign in”. If Active Directory (AD) activity tracing is enabled, a Local Security Authority Subsystem Service (LSASS) exception may occur in the Windows 2019 DC when processing a user’s sign in.
  • Addresses an issue in Microsoft HoloLens that allows users to bypass the lock screen sign in process in some work flows.
