Get your taxes done using TurboTax

I am afraid this is not a Microsoft issue. As I  have already mentioned in my earlier post there are umpteen examples where vendors support their software backward compatible with Window 7 and even XP. Supporting an older OS that is not being updated should be easy. It simply boils down to money. Perhaps Intuit will reconsider its strategy weighing how important is it to retain long-time existing customers.
