I have recently taken over for the IT person in my office and we have a pile of Office packages, but no indicator as to which have been used and which haven't. Is there a way to easily find out if a series of product keys have already been used?
They are all legit, I just need to know if any are unused so that should I need to install office onto a new computer I know if I need to buy a new copy or not.
How to verify if a product key has already been used.
