Let me 1st say that I have been reading this forum for some time and have been trying to learn as much as possible before I ask any dumb questions. I am very interested in learning these methods for my own use. My question(s) is: If I know the edition of the Office 2010 disc I have AND I check the key with the online PID checker, how can I use the information that the onlinePID checker gives me to register the software? Also, when the onlinePID checker says key valid then goes on to show the type of key, registration id, etc....does this mean that the particular key has already been registered or does it mean that it can be registered and that the resulting id would be as it states with the stats???? Thank you in advance. I plan on being a helpful member of this community but I 1st need to learn a lot of stuff so I can be helpful to others.
