Microsoft Windows 10 v1511, 10.0.10537.0

This build leaked on 14/09/2015.

It is not so visually different from the previous build or RTM. It does however contain a new icon in Control Panel for personalization and a new start page for Microsoft Edge.
Also included is Groove Music by default (previous builds had the older Music App).

In Settings you can now ''suspend'' recieving insider builds for 1, 3 or 5 days instead of permanently (which is still available).
