When I click on the icon in the Start Menu, the error is:
The Windows Help And Support can't start
A problem has occured with Windows Help And Support Center. For online help visit Windows Site.
See How to Repair Windows 7 System Files with System File Checker as first-aid.
If a problem is found, better check seriously for viruses.
Go to Start > Run > and then type msconfig, then hit Enter.
Then click on the Services tab. On the list there should be a mention of Help. If this service isn't running, then you won't have any help. Check to see if this service is running.
