I installed the basic C++ tools (precompiled modules, Win10 and 8.1 SDKs, etc) and it has taken 2.5GB out of my C: drive (hardcoded location for the Windows 10 Kit apparently) plus 2GB on my install location.

Then I added NodeJS tools and everything went into the C: drive.

If I select Cordova and other Android and mobile stuff it quickly complains that I do not have enough space - which suggests these tools and SDKs are hardcoded to C: as well. I have not investigated in more detail.

I recall from previous versions that attempting to use junctions would seriously screw up the updater. Given the amount of problems I had to completely uninstall vs2015 a while ago, I totally believe it.
