Stick operates under Windows 7 / Enterprise. Installation with the supplied CD went smoothly and quickly. Have only the CD is inserted and then connected the antenna, so it was in a different review. I want to stick mainly use for transcribing program if I am not in the house. For this, the software that is perfect. It is simple and very user friendly. The supplied antenna is sufficient in Hamburg at all, in this region available stations to receive very good quality. I had almost twice as expensive tried competitor products, this crashed on Windows 7 or showed jerky images. For me a very favorable, well functioning under Windows 7 product.
