Polish computing

How well do you know the pull down menus in Microsoft Word?  Considering that I use Word for Mac, I don't have the menus for PCs memorized at all.  This makes it a particular challenge to use my office computer.  I briefly tried to find a way to get the default language changed to English, but with all the Options/Preference menus in Polish, I couldn't even find the right place to start looking.  I'm managing ok, but its kind of annoying when every word I type is flagged as being misspelled because it is using a Polish dictionary as a reference!
