I’m on Windows 10 now. I’m a little fuzzy on the whole process, it’s been a little while. This thread documents most of my stumbling around to the final success: Photon, local build, on Windows
I lucked out and somehow manually installed it all without @mumblepins well-regarded installer
Turned out to essentially be the same to set up the toolchain on 10 as on win 7, i think, though I found and installed a more recent version of gcc (5.2.1 20151202).
The key for me was the path order stuff as mentioned in that thread
