Windows 10, version 21H1 now available
Windows 10, version 21H1 (also referred to as the Windows 10 May 2021 Update) is scoped to deliver important features that improve security, remote access, and quality—and engineered to provide a fast update experience for those currently running Windows 10, version 2004 or 20H2.
When will this happen:
Windows 10, version 21H1 is available today through Windows Server Update Services (WSUS) and Windows Update for Business, and can be downloaded from Visual Studio Subscriptions, the Software Download Center (via Update Assistant or the Media Creation Tool), and the Volume Licensing Service Center.
For the end user, we are initially taking a measured seeker-based approach to the rollout of this update. We are throttling availability up over the coming weeks to ensure a reliable download experience for all, so the update may not be offered 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 the device will have a good update experience.
How this will affect your organization:
This feature is optional and new for IT administrators to consider using to help with targeting of policies and applications for users on specific devices. You’ll experience a new “Opt-in” capability for this feature in order to evaluate and experience this new functionality. Find out more by reviewing the content and details below.
What you need to do to prepare:
Just as we did for devices updating from Windows 10, version 2004 to version 20H2, we will be delivering Windows 10, version 21H1 via an enablement package to devices running version 2004 or version 20H2—resulting in a fast installation experience for users of those devices. For those updating to Windows 10, version 21H1 from Windows 10, version 1909 and earlier, the process will be similar to previous updates.
