I mean sure, it doesn't work exactly like Linux. It can't.

All _exec functions use the same operating-system function (CreateProcess). I guess they could better emulate Linux using another layer of abstraction but I don't think they do. It is true that large parts of the C library in Windows is there only to emulate Unix like behaviour so as to make porting easier. But it's not meant to emulate Linux exactly (that's what WSL is for).
