Hello! I've decided I want to do a full system restore on my 2010 White Macbook. Its slowing down and I'm fine with clearing away all of that junk to start fresh. But the thing is, I really want to preserve my applications, specifically Microsoft Office Suite. I know those programs are finicky, so I was wondering if there is a way for me to restore my Macbook, but preserve the MS Office Suite in a useable state.
I have a backup drive, but I want to make sure that I can use that to restore my MS Office Suite with the codes and authorization currently on it. I do not currently have the codes I used to purchase it, and I want to make sure I will be able to use the suite after I do a restore.
And my second question, would it be best to stay at Snow Leopard for me, or should I upgrade my OS?
