Releasing Windows 10 22H2 Build 19045.6156 (KB5062649) to the Release Preview Channel for Insiders who are on Windows 10, version 22H2.

This update includes the following features and improvements (items bolded in brackets indicate the area of the change being documented):

• Update resolves an issue impacting the Windows 10 Extended Security Updates (ESU) enrollment wizard. Some users experienced a problem where clicking "Enroll now" caused the wizard window to open, begin loading, and then close unexpectedly. This occurred due to incomplete app registration, which prevented the wizard from loading correctly. This update addresses that issue to ensure a smoother enrollment experience.
  
• [Mobile Operator Profiles] Updated: Country and Operator Settings Asset (COSA) profiles.
  
• [Secure Boot] New! Adds the ability to deploy SKUSiPolicy VBS Anti-rollback protections through the Secure Boot AvailableUpdates registry key.
  
• [Stability issue] Fixed: This update addresses an issue observed in rare cases after installing the May 2025 security update and subsequent updates causing devices to experience stability issues. Some devices became unresponsive and stopped responding in specific scenarios.
