Hello,
i use a laptop with window vista ultimate about a year ago and i never have problem, since now when i start my laptop ,there's a prompt ask me to activation window now or later. first, when i select active now and they have 3 choice for me 1. buy new product key , 2. type different product key, 3. ask for help online. i have chose to type different key . i look at the key product that stick at the bottom of my laptop but that's for vista home premium , so it not run .then i select to active later, when my laptop start i receive a blank screen and there's a phrase say< this window is not genuine, error built code 6oo1> on the bottom right of the screen.
so how can i solve this problem?
