/* FIXME :
1. Make it unicode and ansi compatible with TCHAR
2. Return state it is running if a tree try start it
one more screen saver when we already have one
screen saver running
3. Use GetLongPath or GetPathName so we can use %SystemRoot% in
the key that will make it posible for livecd have a preview screen
saver install.
4. Move the code to winlogon SAS and screen saver must run in
the secuar desktop. But current our Winlogon does not working
well with SAS and with Secure desktop, So I (Magnus Olsen aka GreatLord)
add the code here as w3seek recomandete
