Windows 10 for PCs build 15031 is now available in the Fast ring - here's what's new

While Microsoft was holding its Windows Developer Day event for the Creators Update, it was also preparing a new build for the Fast ring, which is 15031. The build is PC-only, and it contains a few minor new features.

Here's what's new:

Do more at once with the new Compact Overlay window: Ever want to continue watching a movie while switching app to check your email? Or keep an eye on your video chat even as you’re browsing the web? We do all the time! Some tasks don’t require the user’s full attention but is perfect to leave at the corner of the screen so we’re introducing a new compact overlay mode for UWA app developers. When an app window enters compact overlay mode it’ll be shown above other windows so it won’t get blocked. The best part is that compact overlay windows work just like normal windows in all other ways so app developers can tailor the experience with what they already know. Updates to the Movies & TV app and Skype Preview app will take advantage of compact overlay windows in the near future!

Introducing Dynamic Lock: Dynamic Lock automatically locks your Windows 10 PC when you’re not around based the proximity of a Bluetooth-paired phone. If your Bluetooth-paired phone is not found near your PC, Windows turns off the screen and locks the PC after 30 seconds. To enable Dynamic Lock, make sure your phone is paired to your PC via Bluetooth and go to Settings > Accounts > Sign-in options and toggle Dynamic lock to “on”.

NOTE: See known issues below regarding a bug preventing PCs on this build from successfully pairing devices via Bluetooth.

New Share icon: We’re introducing a new share icon. Apps that used the “share” font glyph in Segoe MDL2 assets should get the change automatically. You can read more about the change here.

Windows Game Bar improved full-screen support: We got a ton of feedback on Game Bar and we are continually adding more titles with this support. In this build, we’ve added support for 52 additional games in full-screen mode with Windows game bar. As always, just hit WIN + G to invoke Game Bar to capture a recording or screenshot.

Of course, Microsoft is hoping that you'll participate in the latest Bug Bash, which is happening this week, and ends on the 11th. The original build that it focused on was 15025, but obviously 15031 counts as well. You can participate by going to the Feedback Hub and completing Quests that will help the team to track down bugs.

For those that were hoping for a Windows 10 Mobile build, Windows Insider head Dona Sarkar did confirm that the team is trying to get one out this week. Whether it will be the same build number like it was last time, we don't currently know.
