Microsoft has begun rolling out Windows 10 build 14379 to the Fast ring with several fixes and improvements. The test version of the Windows 10 Anniversary Update is available for PC and Mobile devices.

The new update is only two versions greater than the last build, as such this is just a minor release, it only ships with bug fixes based on feedback.

What’s new on Windows 10 build 14379

On the PC version of the operating system, the company is fixing the Credential UI for computers using high-resolution displays.

Action Center should no longer crash when closing a large amount of notifications. And Sticky Notes gets a fix to work properly with the keyboard.

There is only one known issue on build 14379 for PC: Using Continuum from your phone using the Connect app with your PC won’t work until the next flight.

What’s new on Windows 10 Mobile build 14379

On Windows 10 Mobile, build 14379 fixes UI issues with apps, such as Groove and Cortana, when using the virtual keyboard. And Live Tiles should now show correct images aspect ratio.

As for known issues, nothing hasn’t been fixed since build 14376, which means that you will still find these problems:

  • On Microsoft Edge, you can open PDF, but you can’t interact with PDF files using touch.
  • There are still battery drain issues with devices, including Lumia 830, 930, and 1520.
  • Wi-Fi will continue to disconnect, but Microsoft is working on a fix.
  • Microsoft is testing a new backup format for mobile devices that reduces the size stored on OneDrive. If you do a backup with the latest update, and back to the production release, then the Start layout won’t be preserved.

Windows 10 build 14379 for PC and Mobile is available immediately through the Fast ring. The new preview download and install automatically, but you can always force the update from Settings > Update & security > Windows Update and clicking the Check for updates button.
