Leo mentioned that Windows 8 seemed to him to be a failure, but not everyone agrees. Several Twitter users replied to him saying that they generally liked Windows 8.
There's a utility called RetroUI that doesn't exactly turn it into Windows 7, but does bring back a more traditional Start menu. This could help those who are having difficulty in the Windows 8 interface. This isn't exactly a vote of confidence for the new operating system, though. Leo doesn't see a reason to upgrade if you're happy with Windows 7.
