Following the release of the Windows 10 Insider build 18309 last week, the first 19H1_release build has just showed up on BuildFeed, a service that tracks new Windows 10 builds. The shift from “rs_prerelease” for the previous build 18309 to “19H1_release” for this internal build 18313 suggests that the development of the next Windows 10 has a reached a new milestone internally.

The upcoming “19H1” update for Windows 10 likely won’t be released until April 2019, but Microsoft has already shipped several new features to Windows Insiders. What really caught our eyes so far are the revamped light theme that also comes with a new wallpaper, as well as the Windows Sandbox lightweight VM solution for testing untrusted apps. Microsoft is also testing other changes such as separating Cortana from Windows Search in the task bar, but this may not end up in the final 19H1 release.
Microsoft still has quite some time to test new features with Insiders, but the company better make sure to squash all major bugs before shipping the next major update to all Windows 10 users. As you may know, the Redmond giant had to pause the release of Windows 10 version 1809 after discovering a file deletion bug, and the whole thing was quite a PR disaster for the company. We hope the 19H1 update will be a different story, but Microsoft already seems to be much more cautious about pushing major updates to 700+ million Windows 10 users. Last month, AdDuplex, a cross-promotion network for Windows 10 apps recently said that Windows 10 version 1809 was running on just 6.6% of Windows 10 PCs they measure.
Anyway, now that new 19H1 builds are showing up on Buildfeed this week, we hope that Windows Insiders in the Fast Ring will get a new one this week. As usual, we’ll let you know as soon as the new bits are available.
