With Build 2017 underway in Seattle, Microsoft has issued a new Windows 10 Insider Preview build that delivers a few of the Fall Creators Update features it first showed off earlier today.

“Windows Insiders who have been running builds from our Development Branch over the last few weeks have already been helping test the Windows 10 Fall Creators Update,” Microsoft’s Dona Sarkar writes. “And we are releasing Windows 10 Insider Preview Build 16193 for PC to Windows Insiders in the Fast ring today.”

Here’s what’s new.

Story Remix. Described as an “evolution of the Photos app,” Story Remix is apparently new functionality in that app rather than a new standalone app. People who have downloaded the build tell me that Story Remix is not available in Photos yet, so it probably needs an app update.

Power Throttling in Task Manager. In this build, the “Background Moderated” column in Task Manager has been renamed to “Power Throttling.”

Volume control for individual UWP apps. You can finally control the volume of individual UWP apps in the Sound Mixer, just like real apps.

Beyond this, build 16193 provides various improvements and fixes, and introduces some new known issues. Please check out the Microsoft blog post for more information.
