I had to dig to find this:
I used to be able to get the version number via the Help->About… functionality. Pretty standard Windows pattern.
I wanted to see if the pushed update of Office 2007 SP2 had been applied this morning, and eventually had to look it up.
It is now under the Office logo menu, which I expected. What I didn’t expect is that it’s buried under the Word Options selection at the bottom of that menu.
In the Word Options menu, go to the Resources tab/menu, and the last item in the right pane of that window is the standard “About” information.
