Dear Sandeep ,
thanks again. I actually looked thru the steps on one of my computers with Win 7 ultimate but chickened out for 2 reasons :
1. apparently sometimes the computer decides to lock down if it senses that something may have been tampered with and I was afraid that any changes we made like installing new software etc may be misinterpreted by Win7 and locked down
2. wasnt sure if all other users could still use AC smoothly if the main computer disk was encrypted- this was before you explained that this should not happen, if I understood correctly
but a tutorial from you sure would help!
