Still installing on my VM - takes forever!!!
Had to create a new VM as the old VM's hard drive wasn't big enough.
Had to install Visual Studio 2015 CTP6 before installing the tools
Also, the update to 10046 didn't load at first, so I had to update to it after installing VS and the tools
Phew!

Here's the link:
Windows 10 Technical Preview tools

Here's the Release Notes for the tools:
