Windows 10 Build 19045.6156 Hits Release Preview Channel
Microsoft just rolled out Windows 10 Build 19045.6156 (KB5062649) to the Release Preview Channel. This update targets users on Windows 10 version 22H If you’re part of the Windows Insider Program, it’s time to check out what’s new and improved.
What’s New in This Build?
First off, Microsoft fixed a pesky issue with the Extended Security Updates (ESU) enrollment wizard. Previously, clicking “Enroll now” caused the wizard to open but then crash unexpectedly. This happened because the app registration wasn’t complete. Now, the enrollment experience is much smoother and more reliable.
Additionally, the update refreshes the Country and Operator Settings Asset (COSA) profiles under Mobile Operator Profiles. This ensures better compatibility with mobile networks worldwide.
Major Security and Stability Enhancements
One standout feature is the new Secure Boot enhancement. The update adds the ability to deploy SKU-specific SiPolicy Virtualization-Based Security (VBS) anti-rollback protections. This is done through the Secure Boot AvailableUpdates registry key. In simpler terms, it boosts your system’s defense against firmware rollback attacks.
Moreover, the update tackles a rare but critical stability issue. After the May 2025 security update, some devices became unresponsive in certain scenarios. This patch fixes those stability hiccups, ensuring your device stays responsive and reliable.
Why This Update Matters
Security buffs and IT pros will appreciate the anti-rollback protection addition. It’s a subtle but crucial layer of defense against firmware tampering. Meanwhile, everyday users benefit from smoother ESU enrollment and improved device stability.
“This update addresses an issue impacting the Windows 10 Extended Security Updates (ESU) enrollment wizard.”
“Adds the ability to deploy SKU SiPolicy VBS Anti-rollback protections through the Secure Boot AvailableUpdates registry key.”
In short, Build 19045.6156 is a solid update focused on security, stability, and smoother user experiences. If you’re running Windows 10 22H2 and want to stay ahead, this release is worth installing.
