Windows 10 Build 19045.6029 Rolls Out to Release Preview Channel

Microsoft has just released Windows 10 22H2 Build 19045.6029 (KB5061087) to the Release Preview Channel. This update targets Insiders running Windows 10 version 22H It brings a mix of bug fixes, security improvements, and subtle feature tweaks. Here’s what you need to know.

What’s New in This Build?

One notable addition is the update to Mobile Operator Profiles, specifically the Country and Operator Settings Asset (COSA) profiles. This ensures better network compatibility and smoother mobile connectivity for users.

Additionally, the included curl tool has been upgraded to version 8.13.0, enhancing command-line data transfer capabilities for developers and power users alike.

Major Fixes and Improvements

Microsoft tackled several nagging issues in this release. For example, a problem with Component Object Model (COM) functionality on Windows platforms was fixed. Previously, remote COM activations failed with error 0x8001011, causing frustration for developers relying on this feature.

Another key fix addresses authentication woes. The update resolves device registration issues in the Entra ID Windows Account Manager (WAM) plugin, improving sign-in reliability.

Storage management also gets a boost. The update fixes a bug that prevented complete removal of unused language packs and Feature on Demand packages. This cleanup reduces unnecessary storage use and speeds up Windows Update installations.

Enhancements to User Experience

For users in the European Economic Area (EEA), Microsoft introduced small but handy changes to default browser settings. Now, when setting a new default browser, additional file and link types will be automatically assigned. Plus, the new browser will be pinned to the Taskbar and Start menu by default, unless you opt out.

There’s also a dedicated one-click button to change the default PDF viewer if your browser supports it. This streamlines switching PDF handlers, making it easier for users to customize their experience.

Other Noteworthy Fixes

USB-connected multi-function printers with dual protocol interfaces now scan reliably using built-in OS functions.
Jump lists in the Start Menu no longer disappear unexpectedly.
Resolved an issue where the Start Menu failed to start after updates.
Corrected the version display in Settings > System > About, which previously showed version 2009 instead of 22H
Fixed blue screen crashes on kiosk devices using ForceAutoLogon with Shift Override after lock/unlock cycles.
Addressed system hangs related to Oplock breaks on SMB file shares.

“Additional file and link types will be set for the new default browser, if it registers them.”

“Fixed: An issue where Kiosk devices using the ForceAutoLogon configuration and Shift Override might stop responding with a blue screen.”

Final Thoughts

This Windows 10 update is a solid mix of fixes and subtle improvements, especially for insiders focused on stability and usability. The browser default changes in the EEA show Microsoft’s ongoing attention to regional compliance and user convenience. Meanwhile, the various fixes enhance everyday functionality, from printing to authentication.

For tech enthusiasts and IT pros, this build smooths out some rough edges and keeps Windows 10 22H2 sharp and reliable. If you’re in the Release Preview Channel, expect this update soon.
