I looked it up and this seems like a completely random out of place update. This system is a OneXPlayer 2 Pro handheld console running a cut down Windows 10 build and Steam in big picture mode. This system doesn't have anything else installed, certainly not office.
@nosirrahx Must be some trace somewhere, have you checked C:\Windows\installer (uncheck mask windows system protected files to find it), and look for Office2010 msi trace package. Hope that's help.
