Q: I have been using an evaluation copy of Vista. I am now getting a message that says I need to purchase a copy of Vista. Can I just purchase an activation key or will I need to go buy a copy of Vista?

A: You will need to go purchase a copy of Vista. Be sure that you get the edition of Vista that best suits your needs. Once you buy Vista, may I suggest that you do not upgrade but rather do a Clean Installation of the operating system. Be sure to back up all of your data before installing Vista.
