This new build, 10130, follows just nine days after Insiders gained access to another Fast Ring build - 10122.

It is rumored that Microsoft will RTM Windows 10 in July and with that date approaching their focus on these latest builds is to clean up the UI and take care of any bugs.

In this latest build there is a lot of evidence of the UI being tweaked and cleaned up. Some of these changes we are seeing may not yet be the final state but it appears they are listening to some UI feedback (icons) and not reacting to others (Hamburger Menu on Start Menu/Screen).
