If you have an OEM copy this is what they are there for to provide support for their products. 2 If you brought a Upgrade or Retail version of Vista ring M$ for Technical Support as this is their job to supply the necessary technical support for their products that are not OEM. 3 Ask a question on the Windows Vista Community or even look at questions already asked as this may have already been addresses and a solution posted on that Web Site that is hosted by M$ here http://tinyurl.com/yt8adb Col + 0 Votes Did you ever resolve this?
