No, I don't have any windows computer. But I feel the stick got more and more damaged. So after 482MHz, also the 498MHz didn't work. On the very begining I could watch everything on the laptop. Now it doesn't work on the laptop.
So it got damaged in slow motion.
I will try to buy the same Stick again. Then I will see that all drivers and the new stick will work, I think!
