Windows 10 (19H1) Build Tracker for PCs

We track the history of the development builds released for the 19H1 Feature Update for Windows 10 which will be the seventh overall for Microsoft's client operating system.


Microsoft's Windows Insider Program allows IT pros, system admins and enthusiasts to test pre-release versions of the next major feature update for Windows 10.

The seventh feature update for Windows 10 is known by the code name 19H1 and Microsoft has begun releasing builds in this new development branch as they wrap up work on Redstone 5.

The 19H1 Feature Update for Windows 10 is expected to be released in the March/April 2019 time frame.

There is often no indication that a build will be released until it is announced by the Windows Insider team and there is no schedule for when these builds will be flighted, Microsoft's process of evaluating a build for public release, but weekly releases are the norm in most circumstances.

The builds will be listed in the order they have been released by Microsoft, with the latest build listed first.

Note: Microsoft is retiring the Redstone code name for OS development with the 19H1 designation replacing it for future feature update development. The code name breaks down into two elements with the 19 representing the year of the updates release and the H1 indicating it is going to be released in the first half of 2019. The next update will be code named 19H2 to indicate the second half of 2019 for its release. Subsequent update development cycles are expected to follow similar naming formats.
