I am going to reinstall Mountain Lion using this guide: http://support.apple.com/kb/PH11273 On my computer, I have Microsoft Office programs that I downloaded off of my college website (secured portal). The site was not Digital River or MSDN, but a direct download from an unknown place. If I reset, I assume I will lose it. I'm not sure if my school allows you to download Microsoft Office twice. How would I preserve it? I don't want an exact mirror as I want everything to be at factory settings and just reinstall a few programs.
