Associate a file type or protocol with specific program help
I tried to open the Windows 7 walk through and i got this message so i did what it said and i changed the program from unknown application to Internet Explorer and now i can't open most of my programs how can i change it back to unknown application?
Keys to the Problem Associate a file type or protocol with specific program help
The easiest thing i can suggest is going back to the Default Programs area within the Control Panel under programs and removing the association with Internet Explorer for the file type or protocol that you associated with IE. That may help get things working
right for you. If not then i would suggest using a Restore Point from before you changed the file association.
