Solution 1:

try this Restore the .exe file association in Windows Vista, after incorrectly associating it with another application

Solution 2:

You need to delete this key in the registry (with regedit.exe) in order to make Windows forget the bad file association choice:

HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts\\.exe\\UserChoice

as you can see in the link of loviji's answer.

In general, you delete the key

HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts\\.xyz\UserChoice

where you replace .xyz with either .exe, .bat, .cmd, .com, .lnk, or anything else you need.
