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

  • Good link but some more explanation about what it does would be good.

  • @Sim: You noted that 'the .exe association is corrupted' and the title of the linked article is 'Restore the .exe file association in Windows Vista...' - it also applies to win 7 May 25, 2010 at 4:44
  • +1 for a good link -1 for not bothering to tell what the link points to. (I added a link description)

  • This does not always work. I'm seeing a case where creating a new user profile does not solve the problem although it should as we are fixing HKEY_CURRENT_USER. I'm going a little crazy right now. Microsoft offers this: support.microsoft.com/kb/950505#LetMeFixItMyselfAlways which is more extensive but also not helping.

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


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

In general, you delete the key


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