Windows lifecycle and enforcement updates
Microsoft did not publish any enforcement updates. However, Secure Boot certificates used by most Windows devices will be set to expire by Microsoft starting in June 2026. To avoid disruption, review Microsoft’s guidance and update these certificates in advance.
Each month, Readiness analyzes the newest Patch Tuesday updates and provides detailed, actionable testing guidance. This guidance is based on assessing a large app portfolio and a comprehensive analysis of the Microsoft patches and their potential impact on Windows platforms and application deployments.
This month’s updates require focused testing across network infrastructure, graphics subsystems, and authentication components. There are significant updates to core networking protocols, DirectX graphics functionality, and Bluetooth connectivity that demand immediate validation. These updates affect both client and server environments, with particular attention needed for organizations using Routing and Remote Access Services (RRAS) and those with complex Bluetooth device management requirements.
