Any idea what the 17 updates for Windows 7 64-bit were for today?

My bad. Apparently a lot of them were for Office fixes.

LOL, that one puzzled me at first too. Oops. There was at least one for W7 though. I'm still shocked they haven't included the MP3 file fix in the automatic updates. Why?

It is most likely cause they gave the download available separately. As not everyone will use teh Beta for playing of MP3 files so they would not be affected. ~Alex T.~Windows Desktop Experience MVP~
