Wie kann ich den Windowsordner ermitteln?

[Luckie]

Delphi-Quellcode:

function GetWinDir: String;
const
  UNLEN = MAX_PATH;
var
  Size: DWORD;
begin
  Size := UNLEN + 1;
  SetLength(Result, Size);
  if GetWindowsDirectory(PChar(Result), Size) <> 0 then
    SetLength(Result, Size)
  else
    Result := '';
end;
