Query: Does not support Windows 7

Do not buy this product!It is not, and will never be, supported by Windows 7.I bought this product a few months ago, and it is useless for me now. Norton will only give me a $20 discount to buy 'Ghost 15' which is their only backup solution that will be supported by Windows 7. This means that after I paid $50 for this product they want me to pay another $50 to make it work.Note that most versions of Vista and Windows 7 already come with a built-in backup solution.
