I have just purchased a new HP Pavilion Desktop from Furtureshop. The guy there told me that when i buy it with Vista Premium Home Edition on it, it does not include a Vista CD, like XP did when you bought a pc with XP loaded on it. He tryed to sell me some package that the tech's there will set my computer up and then burn me a backup of Vista OS, incase i ever want to reformat my hard drive and reload vista on to the pc. But that service is another $100. Is there a way that I can make a backup of the OS myself? Any help is appreciated.
