Windows 10 Build 19045.5674 Update Rolled Out to Insiders

01 Apr 2025

Microsoft has announced the release of Windows 10 Build 19045.5674, targeting participants in the Release Preview Channel of their Windows Insider program. This update, labeled as KB5053643, introduces a suite of new features along with several critical fixes aimed at enhancing the overall user experience.

Exciting Features for Windows Insiders

One of the update's highlights is the inclusion of Noto Fonts, which offers expanded support for CJK (Chinese, Japanese, and Korean) characters natively within Windows. This enhancement is set to facilitate better communication and usability for users who rely on these characters in their daily computing tasks.

Additionally, the update includes revisions to the Country and Operator Settings Asset (COSA) profiles, which aim to provide users with improved settings tailored to their specific geographic and operator contexts. This ensures that users receive a more personalized and optimized experience when using their devices in different regions.

Critical Fixes and Improvements

The build addresses several user-reported issues, thereby enhancing the stability and security of the system. A significant fix involves resolving a problem where thumbnails in File Explorer may crash, which was a common frustration for many users. Microsoft has also implemented a fix for printers using Independent Hardware Vendor (IHV) drivers that could previously output incorrect text, thereby enhancing the device's overall print quality and reliability.

Another key enhancement involves improvements in system security. The update now enables system processes to store temporary files in a secure directory, adding an extra layer of security and ensuring that sensitive information is better protected from potential vulnerabilities.

Moreover, there have been improvements to the support for Web Search Providers within the European Economic Area. This is part of Microsoft's strategic initiatives to ensure compliance with various regional regulations and to enhance user experience when accessing web content.

As this build is specifically for the Windows 10 version 22H2, it continues to reinforce Microsoft's commitment to refining and evolving its Windows 10 user experience. Windows Insiders who are part of the Release Preview Channel are encouraged to explore these new features and improvements, offering feedback that will aid in further refinements and the eventual rollout to the broader Windows populace.
