Build 19045.6029 (KB5061087) for Windows 10 drops as the July 2025 Update (preview)

Windows 10 build 19045.6029 (KB5061087) is now available in the Release Preview Channel as part of the upcoming July 2025 update.
It introduces non-security fixes, including enhancements to the default app settings in the EEA, Start menu reliability improvements, USB printer bug fixes, and updates to the curl tool.
This update is part of the final maintenance cycle ahead of Windows 10’s end of support in October 2025.

Windows 10 update KB5061087 (build 19045.6029) is now rolling out in the Release Preview Channel as the first preview for the July 2025 update. This is a maintenance update for Windows 10 22H2 that only introduces various non-security fixes.

According to the official changes, Windows 10 build 19045.6029 mainly focuses on bug fixes and usability improvements. Some of the changes include default browser enhancements in the EEA, fixes for COM activation errors, Start menu reliability, device authentication, and printing issues with certain USB-connected printers. It also updates mobile operator profiles and upgrades “curl” to version 8.13.0.

Windows 10 22H2 build 19045.6029 (KB5061087) changes

These are the new improvements that Microsoft plans to roll out with the July Patch Tuesday Update for Windows 10 22H2.

Default app changes for EEA

Similar to Windows 11, in the past, the “Set default” button only assigned traditional browser types (http, https, .htm, .html). However, now, in the European Economic Area (EEA), to comply with the Digital Markets Act (DMA), it also includes additional link and file types like ftp, read, .mht, .svg, .xhtml, and more on the “Default apps” setting page, if the browser supports them.

Furthermore, when you select a new default browser, it’ll now automatically pin itself to both the Taskbar and Start menu. You can opt out by clearing the corresponding checkboxes during setup on the “Default apps” setting page.

Finally, if a browser can handle PDFs, a separate “Set default for .pdf” button now appears. This lets users make it the default PDF handler with a single click.

Other fixes and improvements

The company is also pushing several fixes and changes for the next monthly update.

Country and Operator Settings Asset (COSA): Country and Operator Settings Asset (COSA) profiles updated.
Apps: Fixed remote COM activation errors (0x8001011) and upgraded curl to version 8.13.0.
Authentication: Fixed device registration issues in Entra ID WAM plugin.
Storage: Unused language packs and “Feature on Demand” packages can now be fully removed, freeing up storage and speeding up Windows Update installations.
Printing: Fixed scanning failures for USB-connected Multi-Function printers with dual protocol interfaces.
Start menu: Resolved issues causing jump lists to disappear and Start Menu failures after updates.
Settings: Fixed incorrect Windows version display on the “About” page
Servicing: Fixed a Blue Screen of Death issue on Kiosk devices using ForceAutoLogon and Shift Override.
File sharing: Addressed system hang issues in SMB share resource acknowledgments.

For clarification, during the early days of development, the company never defined its updates in the Release Preview Channel with the name of the final release. When the updates are ready for the Stable Channel as a preview, they will be known as non-security updates, and it’s not until they become fully available during the Patch Tuesday Update release that the company will label them as the “July 2025 Security Update.”

Important: Usually, the company doesn’t release new features immediately. A new feature advertised as part of an update only marks the beginning of the gradual rollout. It also depends on the geographical location, software, and hardware configuration. For example, because of the rules in Europe, many features take longer to arrive.

Patch Tuesday installation process

To download and install this Windows 11 build, enroll your device in the Release Preview Channel through the “Windows Insider Program” settings. Once you enroll the computer in the program, you can download the build from the “Windows Update” settings by turning on the “Get the latest updates as soon as they’re available” option and clicking the “Check for Updates” button.

As part of the Patch Tuesday development, the software giant is also pushing the updates for Windows 11.

Windows 10 end of support

Microsoft announced the end of support for Windows 10 on October 14, 2025, even though they are still releasing maintenance updates. After this date, Microsoft will no longer provide security updates, bug fixes, features, or technical support for Windows 10. This lack of updates will leave your system vulnerable to security threats and may decrease its performance.

Since the software giant will no longer provide updates or support for Windows 10, you should upgrade to Windows 11 or another operating system, such as Linux Mint, or plan to purchase a new device.

If you want to continue using Windows 10, Microsoft now offers Extended Security Updates (ESU). This service was originally reserved for organizations needing to run older operating systems beyond the official support period, but it is now also offered to regular consumers.
