This is the full, purchased, genuine, untouched version of Vista Home Premium SP1 OEM ripped as a bootable ISO image.Get rid of the crap that comes with a new computer! I have it installed and activated on my HP Pavilion using the cd key that came with the computer.I can see no reason that it will not work on other makes.It is important to note that you will need to get the drivers for your machine before attempting an install. I hope it comes in useful for you all. No password. A lot of time went into uploading this so a thanks would be nice
