Vista activation I am more than happy to find this site where experts discuss things . Let me give you all a biefing , i am bryan gopan ( working with dell intl india) . I have MSD N access given by my company . I did had my acer system running with VIsta ultimate for almost 8 months which i have doanloaded from MSDN . Since last 2 weeks i am getting pop up saying " my license will expire in so and so days " , "please back up your data and install any other version of vista . NOw this is really strange as i never heard of any trial versions in MSDN . To my surprise under my computer > properties > it says my OS is actvated ... I also tried getting a different product key and putting it in chnage your product key ( it goes through the process and says congratulations you are good to go ,but the pop up still appears.) *****NOW ITS ZERO DAYS AND I CANNOT ACCESS INTERNET < EVERY THING ELSE WORKS FINE **** ( When i boot into XP in the same machine , internet works good ) I also tried contacting MSDN Customer service , they are asking me to back up and flash ... Now i wanna know is that the only alternative .
