How about win10 Build 9865?

At TechEd Europe, Microsoft Joe Belfiore demonstrated the upcoming new touchpad experience for the Windows 10 Technology Preview update, new build number Build 9865.

In Windows 10, Microsoft added touchpad gestures, including: three finger slides to minimize all active windows, and top-up recovery windows; three-finger strokes can also be used to activate the Task View interface; Finger left and right stroke switching applications. These are similar to the touchpad gesture settings for Mac OS X. Windows 10 has also improved the multi-screen window snapping, and now dragging to the edge of the screen will display a close-up prompt for the layout window.
Joe Belfiore said these improvements will be in the next Windows Insider update. According to Microsoft's update frequency, the next Windows 10 Technology Preview update does not have to wait too long.
