When considering moving to a different operating system it is always good to ask “Are the programs I have purchased compatible?”.  Sometimes however you can expose just how foolish you have been in your purchasing decisions, such is the case in a question on Yahoo Answers:

Is XP Antivirus 2009 compatible with Vista?

I got a new computer running windows Vista but I already paid for XP antivirus 2009 on my old computer.Will I be able to transfer it to my new one or is only compatible with windows XP?

I have paid $50 for that program and I’m going to use it if I can.
