What you need to know
- Microsoft has started the process of automatically updating PCs running Windows 10 version 20H2 to version 21H2.
- This is phase one of a rollout that uses machine learning to target devices that are ready to receive an update.
- Windows 10 version 20H2 reaches its end of support in May 2022.
Here's Microsoft's breakdown of the rollout as outlined by a support document:
We also started the first phase in our rollout for machine learning (ML) training, targeting devices on Windows 10, version 20H2 that are approaching end of servicing to update automatically to Windows 10, version 21H2. We will continue to train our machine learning model through all phases to intelligently rollout new versions of Windows 10, and deliver a smooth update experience.
Windows 10 version 21H2 is already available for select devices running Windows 10 version 2004 or higher. People with supported devices can manually seek an update to get the newer version of Windows onto their PCs.
There aren't any major new features in Windows 10 version 21H2. In fact, there aren't any notable changes that people should have to get used to. The update also removes the ability to sync activities across devices through the Timeline feature.
Importantly, Windows 10 version 21H2 will be supported after Windows 10 version 20H2 reaches its end of life. Windows 10 version 21H2 will be supported up to July 13, 2023.
Of course, people with PCs that meet the minimum requirements of Windows 11 can upgrade to the latest operating system from Microsoft.
