Yeah or i would want something that would encrypt the operating system.This is how it would work, turn computer on the decryption prog runs from memory and asks what partitions i want to decrypt and asks for password.I know there are progs that do do this but i cant find any,so thats why i came here for help.The reason i want this type of security is i have my pc in my bedroom and is phsically accessable,i have added the syskey start up password and added a win xp user password but i dont wanna rely on windows security and i know encryption is secure.
