So what exactly is Windows 10 KB5055518?

Windows 10 Build 19045.5737 brings several new features and improvements, fixes, and, unfortunately, some new problems. Microsoft noted that this update addresses security issues for your Windows operating system.

Windows now includes Noto CJK fonts, which cover Chinese, Japanese, and Korean characters. This improves text rendering and compatibility for users who rely on these languages.

The Country and Operator Settings Asset (COSA) profiles have been updated to ensure better compatibility and performance for mobile network users.

Windows Search now offers improved functionality for users in the European Economic Area (EEA), making web search results more accessible. If you’re using the Microsoft Bing app for web searches in Windows Search, it’ll now open results in your default browser instead of Bing’s own interface.

To enhance security, system processes now store temporary files in a protected directory (C:\Windows\SystemTemp). This reduces the risk of unauthorized access by requiring applications to use either the GetTempPath2 API or .NET’s GetTempPath API.

What more, Certain Get-Help troubleshooters that previously failed to run in Remote Desktop sessions are now functional again. A bug that caused thumbnails in File Explorer to crash, displaying blank white pages instead of the correct preview, has been resolved.

In addition, A bug affecting USB-connected dual-mode printers that support both US Print and IPP Over USB protocols has been fixed. Previously, these printers could output incorrect or unwanted text unexpectedly.

Microsoft has also reminded users that after October 14, 2025, Windows 10 will no longer receive free updates, technical support, or security fixes. While the operating system will continue to function, Microsoft recommends upgrading to Windows 11 to ensure ongoing support and security updates.

Microsoft noted two known issues. Some devices with certain Citrix components (especially Citrix Session Recording Agent version 2411) might encounter problems installing the January Windows update. The Windows Event Viewer might display an error related to SgrmBroker.exe, on devices that have installed Windows updates released January 14, 2025 or later. Microsoft is investigating and plans to release a fix upcoming release.
