[Python-Dev] Windows 10 build agent failures

[Ivan Pozdeev]

For me, Tcl/Tk failed to build with SDK 10.0.16299.0 , I had to 
expicitly fall back to 10.0.15063.0 ( 
https://stackoverflow.com/questions/48559337/error-when-building-tcltk-in-visual-studio-2017 
). May be related if VS was (auto)updated on the builders.||
