Booted my pc today to get the windows vista ultimate product key you typed is invalid message and the only thing i could do was open a web browser. Found this site and the magic jelly bean thing but after entering the code i get an error code: 0xC004E003 come up. Tried searching it but the only suggestion required full use of windows and after eventually working out how to get control panel to open up in this stupid reduced function form it didn't work. Any ideas??
