Microsoft has rolled out the much-awaited Windows 10 KB5063709 update, targeting improvements for versions 22H2 and 21H2. This update, rich in security and functionality enhancements, promises a smooth transformation for enterprise and personal users alike. With a host of seven distinct fixes, this cumulative update underscores Microsoft's commitment to maintaining a robust operating system.
Key Enhancements and Fixes
A pivotal highlight of KB5063709 is its resolution of a bug that hindered users from enrolling in the Extended Security Updates (ESU) service. The persistent issue that surfaced when users clicked 'Enroll now'—only to witness an abrupt closure of the enrollment wizard—has been deftly addressed. By fixing this, Microsoft has ensured continuity of security support beyond the standard end-of-service dates, an essential feature for businesses relying on extended support.
Additionally, KB5063709 introduces valuable enhancements to Secure Boot mechanisms. Notably, it incorporates SKUSiPolicy VBS anti-rollback protections, an addition that is accessible through the registry. This feature fortifies system integrity and assures a new layer of protection via the Secure Boot infrastructure.
The update also includes refreshed Mobile Operator Profiles with the updated Country and Operator Settings Asset (COSA) profiles, providing improved compatibility and reliability for network operations. Alongside these, critical core file system stability issues detected since the previous May 2025 security update have been resolved, addressing device unresponsiveness.
Addressing Input Challenges
The KB5063709 update also troubleshoots multiple input-related bugs that have plagued users. A problematic inability to select words, difficulties with the emoji panel search feature, and a malfunction of various phonetic input methods—such as Hindi and Marathi keyboards—have all been corrected. These improvements aim to ensure a more fluid interaction and seamless user experience.
Windows 10 users on the 22H2 version will transition to build 19045.6216, whereas those on 21H2 will update to build 19044.6216. Installation can be readily initiated through the standard Settings > Windows Update pathway. The necessitated restart can be appropriately scheduled, according to user preference, ensuring minimal disruption.
No Known Issues
Microsoft has confirmed that this update does not introduce any new issues—a testament to its thorough testing and attention to detail. Regularly ensuring devices are up-to-date remains essential, and with this update, Microsoft's flagship operating system is positioned to offer enhanced performance and security integrity.
