I have an Alienware m15x that I bought from Dell in 2009. I customized my order when I bought it so it came with Microsoft Office pre-installed. Its been getting sluggish and I got hijacked by some adware virus due to my carelessness so rather than figure out how to get rid of it and clean my system I've decided to start fresh and re-install Windows 7. Is Office backed up in my restore partition so if I restore it, Office will be re-installed too?
