Just run Windows in a VM and cut off internet access. Use the windows offline updater periodically (not nearly as important since you don't have internet; still useful if you are going to import foreign files into the vm). http://www.wsusoffline.net/ http://www.wsusoffline.net/. You'll need a different windows scapegoat machine to use wsusoffline though. I don't think there is a linux version. Also, office 2010 on wine/crossover is perfectly usable for light work. Office 2013 is also somewhat supported these days.
