Microsoft has released their first Windows 10 21H1 preview today, build 20150, to Insiders on the Dev (Fast) channel.
With Windows 10 version 2004 (20H1) released last month, and a Windows Insider 20H2 build released yesterday on the Beta channel, Microsoft is today offering the 21H1 development branch to Insiders on the Dev ring.
If you are not familiar with the new channel names, Microsoft recently overhauled the Windows Insider program to move away from rings and to channels, as listed below.
- Fast Ring becomes Dev Channel.
- Slow Ring becomes Beta Channel
- Release Preview Ring becomes Release Preview Channel.
Insiders in the Dev (Fast) channel who wish to upgrade can go into Windows Update and check for new updates.
While this release is mostly bug fixes, Microsoft is rolling out some new features for the Windows Subsystem for Linux that allow you to configure it from the command line and use Linux applications that use a GPU, such as TensorFlow.
Microsoft is also rolling out a search feature for the Default apps settings screen that lets you quickly find an extension that you wish to change the default program.
When we tested this feature in the past, the search was quite sluggish to use, and you would have significant delays, especially if you had a lot of configured extensions.
Microsoft states that with this release, they have improved performance in the search box.
