I know it seems like a stupid question. But my problem requires a work around. I bought an OEM copy of Vista and after one install the disk is all cracked up and chipped beyond use. Apparently MS uses cheap garbage disks. Plus windows disks always seem to to cycle at a much higher RPM than others so there is no way it could handle that stress since it's already a weak piece of garbage. I've only had three optical disks break in my lifetime. Two copies of XP and my recent Vista 64. A power surge fried my my main IDE and wiped my drive so I need to re-format, but I can't because the disk is too brittle to withstand the first installation. It's almost as if MS deceptively engineers the disks to break. I tried the vendor but sending me a $1 piece of plastic isn't viable and MS seems to be run by investors that don't really wish to do anything except run MS into the ground. They don't care about the quality of their OS nor their commercial consumers. I THOUGHT I was paying for what's on the disk. NOT the disk. Anyone here have any ideas or know what I can to get it replaced. Even though I registered it with MS they won't support it. Finally got a hold of MS but that keep shuffling me around. They want $30 dollars for a replacement disk. It says don't make illegal copies on the disk and at first I respected that, but you give what you get. So I'm gonna disregard that and make 6,000 copies. If a couple thousand of them happen to disappear... it's not problem. Things get lost/stolen.
Other option is to just download the iso from torrent sites, and use your legit key. I don't recommend this, but its a last resort, and since you own a key I Believe you should be fine.
