Title: On Windows the salt-minion seems to run just fine even as a regular user...

....

It's possible to check for an admin user using ctypes- print ctypes.windll.shell32.IsUserAnAdmin(), but it isn't helpful because unless the administrator opened up the terminal as an admin, it will always return 0.

So unless further testing reveals that salt MUST be run as an administrator, check_root() should just return true when on Windows.
