Thanks AsmMan,

Found 
http://msdn.microsoft.com/en-us/library/windows/desktop/ms724432%28v=vs.85%29.aspx 
and with your help, now understand :)

The syntax below prints a blank after my username, so the slice 
seems a bit too long :O So my "final solution" looks like:

 module main;

 import std.stdio;
 import std.c.windows.windows;

 pragma(lib, "user32.lib");
 pragma(lib, "Advapi32");

 void main(string[] args)
 {
    WCHAR lpwszUsername[254];
    DWORD dUsername2 = 254;
    GetUserNameW(lpwszUsername.ptr, &dUsername2);
    writefln("Welcome userW %s", lpwszUsername[0..(dUsername2 - 
1));
    writeln();
  }

THANKS again!!!

GetUserNameW() return a zero on error and non-zero on success. 
The actual number of bytes copied into lpwszUsernam is in 
dUsername2.

auto userName = lpwszUsername[0..dUsername2];
