Hi all. I got this Laptop a year or so ago, only use it for watching movies hooked up to TV and emergency = Don't give a rat's ass about it. After 3 months or something, the power went out one night and since then the validation it had I guess is not good anymore? Anyway I am hoping to not spend much time on this, the laptop works fine, it is just annoying when watching a movie to have the "Windows must be reinstalled" pop-up show up, so at minimum I would like to toast that, if I can also fool the OS to think it is genuine that would be a bonus I guess, definitely don't want to install another OS, re-install etc. What I have is: Windows Vista Home Premium Service Pack 2 HP Compaq Presario A900 Notebook Message in corner of screen = Build 6002, This copy of Windows in not genuine Thanks in advance!
