Overview
- Microsoft’s January security updates triggered two major problems now addressed: Remote Desktop sign-in failures across multiple Windows builds and a shutdown or hibernate failure on some Windows 11 23H2 PCs with Secure Launch.
- Remote connection issues affected the Windows App and cloud-hosted sessions such as Azure Virtual Desktop and Windows 365, with authentication breaking before a session was created.
- Key OOB patches include KB5077744 for Windows 11 25H2/24H2, KB5077797 for Windows 11 23H2, KB5077796 for Windows 10 ESU/LTSC, and server fixes KB5077793 (Server 2025), KB5077800 (Server 2022), and KB5077795 (Server 2019).
- Enterprises that cannot install the OOB updates can deploy a Known Issue Rollback via Group Policy, and earlier guidance allowed manual shutdown using the command 'shutdown /s /t 0' on affected 23H2 devices.
- Microsoft acknowledges an unresolved Outlook Classic crash affecting POP accounts, and independent reports cite unconfirmed UI glitches like transient black screens, wallpaper resets, and desktop.ini issues.
