What’s New in Windows 10 Build 19045.6937?

Since Windows 10 is now out of mainstream support, no new features are included. However, this build delivers several critical bug fixes:

• Fixes an issue where Windows 10 does not shut down correctly, a problem reported after the January 2026 Patch Tuesday (KB5073724).
• Resolves hibernation issues where some devices rebooted automatically instead of shutting down or entering a low-power state.
• Addresses power consumption problems caused by devices failing to enter hibernation.

Impact of Previous Updates

Users reported that updates from January 2026 and even December 2025 caused stability issues, including:

• Slow system performance
• Lower FPS during gaming sessions
• Taskbar freezing

These issues predominantly affected Windows 10 PCs with Nvidia GPUs. While Microsoft has not disclosed the list of affected GPUs, installing KB5075912 is recommended if you are experiencing stability issues.

File Explorer and Desktop.ini Fix

A bug in the January 2026 Update caused File Explorer to ignore folder customizations stored in desktop.ini. This affected the LocalizedResourceName setting, leading to folders displaying their raw directory names instead of user-defined friendly names.

For example, IT admins who maintained a shared folder named “Printer_drivers_2025_HP_Dell” but used desktop.ini to display it as “Printer Archive” faced confusion when the raw name appeared instead. The KB5075912 update resolves this issue, restoring proper functionality to desktop.ini and File Explorer.

Known Issues in Windows 10 KB5073724

Microsoft has confirmed that there are no new known issues in KB5073724. This is expected as Windows 10 is now in its Extended Security Updates phase, focusing primarily on security fixes.

The February 2026 Patch Tuesday addresses 58 security vulnerabilities, including five critical issues. Below is a summary of the security fixes included:

• Critical security patches for vulnerabilities in system components.
• Enhancements to protect against malware and unauthorized access.

If you encounter any specific issues, feel free to report them, and Microsoft will investigate further.
