 priviledge on Windows

[Message part 1 (text/plain, inline)]

In my new patch, if we received the ERROR_INVALID_PARAMETER, we will try to
create the symbolic link again without the new flag.
Isn't that ok for now?
The Windows version API has returned the same thing from the start of
Windows 10 so we pretty much can't detect the Windows version by using it.
Unless we read the information directly from the registry and parse it by
ourselves, which is something I would like to avoid.
