I'm using Vista not sure about getting Win 7. My Vista CD cracked and MS didn't want to replace it. I know it's not MS's fault but rather the shop which sold me the OEM CD without customer end support but I'm disappointed nonetheless. Some OEM come with customer support i.e MS would replace damaged disc for a price I was just unlucky enough to buy the OEM without end support I suspect the shop was selling me Vista copy which should otherwise not be sold separately.
