Windows 11 KB5074109 has caused several issues for users, particularly those with Nvidia GPUs, including black screens, Outlook freezing with POP accounts, and problems with File Explorer's desktop.ini settings. Users have reported random black screens and desktop freezes after installing the update, with some finding temporary relief by changing their monitor's DisplayPort mode. Outlook Classic has been problematic, remaining active in the background and freezing shortly after opening, prompting users to terminate the process in Task Manager or uninstall the update. Additionally, the update disrupts Azure Virtual Desktop functionality, leading to sign-in failures and connection issues. Microsoft has acknowledged these problems and is investigating solutions, including a Known Issue Rollback for AVD. The update also breaks the LocalizedResourceName directive in File Explorer, preventing folder name customization. Users can uninstall the update through Settings, but this may expose them to security vulnerabilities.

Users with Nvidia GPUs are experiencing decreased gaming performance after the January 2026 Windows update (KB5074109), which was intended to enhance security and address vulnerabilities. Reported issues include drops in frames per second (FPS), black screen freezes, display hangs, and driver crashes related to nvlddmkm errors. Nvidia has released a new GPU driver to address these problems. A temporary solution for affected users is to uninstall the KB5074109 update, although it is a security patch that may need to be reinstalled later. Users can also update their Nvidia drivers to the latest hotfix version and use Display Driver Uninstaller (DDU) in Safe Mode for better results. It is recommended to pause Windows updates until a fix is provided by Microsoft.

Microsoft has raised concerns about the shutdown process of Windows PCs, indicating complications following the January 13, 2026, security update. PCs with Secure Launch may fail to shut down or hibernate, instead restarting unexpectedly. A temporary solution is to use the Command Prompt with the command shutdown /s /t 0 for shutting down, but there is no workaround for the hibernation issue. Microsoft recommends saving work and shutting down devices to avoid power loss. Additionally, some users are facing credential prompt failures during Remote Desktop connections, affecting services like Azure Virtual Desktop and Windows 365. Alternatives include using the Remote Desktop client for Windows or the Windows App Web Client. An emergency update is expected to resolve these issues.
