HI, I have W 7 upgrade, which MS say can do all if I want to professional wipe (format ) my drive. They have a code to put. Last week I took the computer to Best Buy and Geek Squad and they would do a format and install. It seems this problem is from the Compaq, HP and other priority machines. I have been here before. I am now finding my program, IsAdminOptons, showing I am not the ADMIN. Just had to take ownership and now I have this problem. I will call MS tomorrow. Keeping you posted. Avie
