Does Microsoft Office use any marks/keys in saved files, that can track the computer and software license using which file was saved? E.g.: I use Office at work and save files on pendrive. When I'm home I recall to check something and introduce little modifications. I'd save this file using MS Office Home and Student license, but at work I will be redistributing this file and it should look as it was saved at work, with company's license (not my private). Will saving it at work once again wipe license marks from home (if any exist)?
