Windows 10 build 16170

Windows 10 build 16170 is the first public build of the Windows 10 Fall Creators Update (codename "Redstone 3") development branch. It was released on 2017-04-07 to the Windows Insiders in the Fast ring. This build doesn't contain major changes from the Creators Update's RTM build (albeit with bug fixes and enhancements to this build), as Microsoft is working internally under the hood improvements to OneCore, just like every other previous feature updates.
