please delete, wrong section

Hey guys and gals,
 
I've been trying to install sonar 5 on my newish lap top and have run into problems getting the driver set before I go ahead with the install. I have had it installed on my desk top previously.
 
 
I think the newer version of windows I'm running does not marry up with the instructions in the manual.
 
ie once I get to the control panel I can't find the 'performance & maintenance' section it asks for to make changes to the 'driver signing option'.
If I install without making those changes at the begining I can't arm tracks to record. 
Sorry if this is a daft question...
 
 
Your help is appreciated
 
 
Andrew
