Dan has an HP Touchsmart PC and after a recent Windows 7 update, he can't connect to the internet. Leo says that could be a bad update. If he can remove it, he should try that. He may have to do a system restore. That should roll back the update. If that doesn't work, then Dan should back up his data, and do a complete system recover. Once that's done, he should update it completely. If all that doesn't work, then it's a hardware issue.
