The update, which will take a staggered and measured approach to rollout, introduces several new security-oriented features, namely multi-camera support for Windows Hello, Windows Defender Application Guard, and a group policy service. “In the current environment, we know that you continue to rely on your PCs more than ever. As a result, we are initially taking a measured seeker-based approach to the rollout of the May 2021 Update,” said Microsoft’s vice president for program management, Windows servicing and delivery, John Cable. “We are throttling availability up over the coming weeks to ensure a reliable download experience for all, so the update may not be offered to you right away. Additionally, some devices might have a compatibility issue for which a safeguard hold is in place. In these cases, we will not offer the update until we are confident that you will have a good update experience.”
