Recently I have had a few clients stating they are getting prompted by Microsoft that their version of Vista will be ending soon. Initially I thought they were mistaken as they quite possibly had the beta version of Windows 7 installed which of course is ending soon. After checking the error personally, I have learned it was because they had a pre-release version of Service Pack 2 installed. Upon attempts to uninstall this pre-release failed and so off I went searching for the solution which Microsoft has released here.
