This is a short note to help those folks who are having problems with opening Word documents after a critical update from Windows last week. It appears it is unique to folks with some specific HP software.
After studying it, I would recommend going to Add/Remove Programs and remove the HP Share-to-Web program (unless you are really using that feature…most people don’t). If you do use that feature or want to learn more about the cause and fix for this problem. Visit Microsoft’s Support site and read their article.
