Problem reports where making the rounds shortly after the final release of the Windows 7 operating system. It is not unusual that some users report problems when installing a new operating system or upgrading their old OS to a new one. Windows 7 in this regard did not get a lot of bad press except for a problem that got reported quite frequently by Windows Vista users who tried to perform an upgrade to Windows 7. These Windows Vista users were experiencing an error at exactly 62% of the update.
Windows performed an automatic rollback to Windows Vista at this point leaving the user puzzled and confused. Some users even experienced an endless reboot problem which would initiate the upgrade process again only to fail again at 62%.
Microsoft has released a Fix-It solution for the problem that the Vista to Windows 7 upgrade hangs at 62%. Fix-It solutions are one-click solutions that will correct a problem that was experienced by the user before. In this case the Vista user needs to click on the Fix-It button on the Microsoft support website after the upgrade failed at 62% to fix the issue and initiate the upgrade again.
Experienced users can also fix the problem manually by following the steps detailed at the very same support page:
