Microsoft is now rolling out Windows 10 build 19042.330 for devices enrolled in the Beta Channel (formerly Slow ring) of the Windows Insider Program. This is the first build releasing to testers, and it’s a small update with fixes and changes.
The company is making the preview available for “seekers,” which means that you’ll have to manually trigger the update from Settings > Update & Security > Windows Update and choose to download and install 20H2.
Also, the company explains that is making some changes, so that anyone who chooses to install 20H2 builds will receive the features plans for Windows 10 20H2 as they become available. In the past, only a subset of users receive all the features, and based of feedback, this is changing with the new update.
