It is faster if you use SHFileOperationW directly on Windows (and 
also it will ignore readonly attributes):

//not tested
void winrmdir(string path)
{
     import core.sys.windows.shellapi;
     import std.exception : enforce;
     import std.file: FileException;
     import std.utf: toUTF16;

     auto shpath = (path ~ "\0\0").toUTF16();
     SHFILEOPSTRUCTW s;
     s.wFunc = FO_DELETE;
     s.pFrom = shpath.ptr;
     s.fFlags = FOF_NOCONFIRMATION | FOF_SILENT | FOF_NOERRORUI;
     enforce!FileException(SHFileOperationW(&s) == 0 && 
!s.fAnyOperationsAborted);
}
