Latest Updates from Microsoft: Windows 10 and Windows 11 Release Previews
Microsoft has recently introduced an update to the Windows 10 Release Preview build 19045.6156, now updated to build 19045.6159 (KB5062649), primarily focusing on resolving existing issues rather than launching new features. This release is particularly notable for addressing problems with the Extended Security Updates (ESU) enrollment wizard, allowing users to more effectively engage with the ESU program.
In addition to improving ESU functionality, this update also includes enhancements to Secure Boot and promises overall “stability fixes”following the Patch Tuesday updates of July 2025.
Changelog Highlights for Windows 10 Build 19045.6159:
- ESU Enrollment Wizard: This update resolves a specific issue where users faced problems when clicking “Enroll now.” The wizard would unexpectedly close due to incomplete app registration, disrupting the enrollment process. With this latest patch, users will have a smoother experience enrolling for Extended Security Updates.
- Mobile Operator Profiles: Updated country and operator settings have been implemented to enhance usability for mobile operators.
- Secure Boot Enhancements: A new feature allowing the deployment of WeUSiPolicy VBS Anti-rollback protections via the Secure Boot AvailableUpdates registry key has been introduced.
