Just wanted to let you guys know do. DO NOT install this on any of your XP machines. This is a very buggy and useless product for XP if you ask me. I had to format my friends PC because of this. Maximum PC even has a column in the'ask the doctor' section of the mag explaining a users exact problem that my friend had with this product. It absolutely and totally stops the computer from booting to the log in screen. Just a word to the wise fellas. Stay away.
