I've been ignoring/closing this suspicious looking pop-up for many weeks now although those pop-ups have been appearing less frequently for the last few weeks. Microsoft Office 2010 Starter came preinstalled on my computer & although I don't use it every
day I do use it often. Just as a follow-up, today I opened it only to find that all of the options that were previously available are no longer there, i.e. no choice of font size, no option to cut & paste, no choice of typeface, NADA! All there is is
a blank document page where you can type text & & save it, nothing more. In retrospect it might now be a good idea to install the update since it seems to have been verified. But it would still be good for Microsoft to give some type of official notification
when they change their update forms so we don't all have to confront these questions again.
