Microsoft has rolled out Windows 10 22H2 Build 19045.6029 (KB5061087) to the Release Preview Channel, bringing a mix of performance improvements, security enhancements, and quality-of-life fixes. This June 2025 update demonstrates Microsoft's continued commitment to refining Windows 10 even as Windows 11 gains traction.

Core Improvements in Build 19045.6029

The update delivers several notable under-the-hood enhancements:

  • Start Menu Reliability Fixes: Resolved an issue causing intermittent crashes when searching for apps

  3. Remote code execution possibilities through malicious Office documents

Enterprise administrators will appreciate the improved Group Policy processing that now logs detailed error information when policies fail to apply.

  • Preserves user-configured defaults more reliably
  • Provides clearer notifications when resetting defaults is necessary
  • Offers a streamlined interface for reapplying preferences

Update Process and Compatibility

The KB5061087 package weighs approximately 650MB for most systems. Microsoft reports successful installation on:

  • 98.7% of test devices
  • All currently supported CPU architectures
  • Systems with as little as 2GB RAM

Potential Update Issues

Early adopters should note:

  • Some third-party antivirus software may require updates
  • Rare display driver conflicts have been reported

Microsoft recommends creating a system restore point before installing the update, particularly for mission-critical systems.

Looking Ahead

This update reinforces Windows 10's position as a stable, mature platform while incorporating lessons learned from Windows 11 development. The focus on security and enterprise management suggests Microsoft intends to maintain Windows 10 as a viable option for organizations not yet ready to transition.

For most users, the update should install seamlessly through Windows Update, delivering incremental but meaningful improvements to their daily computing experience.
