On Windows, it's not up to me to decide where users will keep my stuff, and where it will work. Users decide.

For a software to work fine on Windows, it must support spaces in files and paths. Also Unicode in files and paths.

VBScript does, GNU Make doesn't.

If you use make to setup stuff, it's very possible you'll need to access "c:\Users\All Users" which does contain space in username. Also "c:\Program Files (x86)\Common Files" which contain more than one.

You can try the 8.3 convention,

DOCUME~1 Documents

or

<SYMLINKD> ALLUSE~1 All Users [C:\ProgramData]
