That being said, both M-! and call-process succeed in invoking this
"program" okay, so there's something Eshell does that gets in the way.
Here's the backtrace from the error:

Jim, why does Eshell want to read the executable file winget.exe? If
that's because it wants to find the signature by which it will deduce
the interpreter, then doing that for zero-size files is not useful,
and should probably be skipped?
