Recently many users all round the world have been facing this very strange issue where the updrade from Windows Vista to Windows 7 stucks at 62%. Users complained that the upgrade just sits there at 62% no matter how long you wait.

However, Microsoft has quickly identified it as some issue with the Windows IPv6 helper service that stops responding during an update which causes it to get stuck at 62% and have come up with a solution.

Warning: Use this solution only if you are experiencing the exact problem. i.e. Upgrade from Windows Vista to Windows 7 stucks specifically at 62%. Do not use this solution otherwise.

Solution:

Click , right-click Computer, and then click Properties.

Thanks to Lee Mathews and Microsoft for providing the solution.
