The May 2021 Update is available initially to select devices running Windows 10, version 2004 or later who are interested in experiencing the latest feature updates and are ready to install this release on their device. In these cases, we will not offer the update until we are confident that you will have a good update experience. Additionally, some devices might have a compatibility issue for which a safeguard hold is in place. 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.

As a result, we are initially taking a measured seeker-based approach to the rollout of the May 2021 Update. In the current environment, we know that you continue to rely on your PCs more than ever. Our approach to update availability and rollout My post today shares details on our measured rollout approach, how you can get the update and some overall information on Windows. We have released and evaluated preview builds through the Windows Insider Program over the past months and, based on the feedback gathered from our Insider community, we are now ready to begin a phased rollout.

The May 2021 Update is purposely scoped to deliver important features that improve security, remote access and quality-and engineered to provide a fast update experience. As I noted when we first announced the May 2021 Update in February, we grounded this update on the needs expressed by you, our customers, over the past year of continued remote work, learning and play.

Today marks the beginning of Windows 10, version 21H1 availability.
