Is there a product key finder for a PC?
Is there a way I can grab Office 2007 installation key from the already-installed and activated software? I no longer have the key, and I want to format the system, but I would like to reinstall the Office.
Also, as long as I activate it on only one computer, can/should I install it as many as times as I want? (I am thinking about Microsoft Virtual Machine that comes with 90-day expiry.)
