Hey! I'm new here and just installed Windows 7 today! It looks great and functions really well, but I have a big problem that if I don't solve it I have to install Vista again. The problem is that all the USB inputs on the computer aren't working ... I can't use my mouse I can't use anything that connects with USB. In the Device Manager it tell me I have Code 19, which is a problem with the registry files. Can anyone please help me solve this problem? if not I have no choice and need to go back to Vista thanks for you help!
