I do not use the online product.
I agree with the OP: TT is about tax filing assistance, and should not force desktop users to upgrade. I wonder if this requirement comes with some security guarantees? Unlikely, what we will get after spending money on win10 is TT assumes no responsibility for security on your end regardless the OS. Let there be no doubt, we are responsible for the security on our end, not TT. Lastly, I run an updated security suite on my PC, so my concerns are minimal. Does that protect me from every exploit? No, but neither does upgrading as the exploits continue.
I will look at my options, non-TT, prior to upgrading to win10.
