I stumbled upon Windows Pgm. that does this. Normally it's too expensive, but is $0 for one day, Feb 13EDITED. Good until midnight pacific time (-8) Feb 13.
If its after the 13 th, the try searching this "Aiseesoft iTunes backup genius". Warning, their full price is too high, I'd prefer $10 to their $99. For me, the freebie was a nice touch.
