Windows 7, All Files Now Have .lnk Extension And Won't Open.

Help please. My wife just ran her Avast Cleanup Premium, and now all shortcuts and program files have a .lnk extension, and won't open. Every time I try to open something I get the 'can't open file, need to know what program created it" stuff. I think it's a corrupt registry thing, but I can't even open the regedit.exe. Help Please. Thanks, Ed

 

Hi Tim, Thanks for responding. I already tried that, but my regedit file wouldn't open. I think it's fixed though. I downloaded the Option 2, Windows 7 LNK and EXE Registry Fix from this following link, and was surprised that it worked. All icons are restored to normal and they open nicely.

You have helped me in the past also, and I really appreciate it. Best, Ed
