Good link but some more explanation about what it does would be good. – Sim May 25 '10 at 4:39
@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 – SnOrfus May 25 '10 at 4:44
+1 for a good link -1 for not bothering to tell what the link points to. (I added a link description) – Nifle May 25 '10 at 7:36
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: which is more extensive but also not helping. – simbabque Jun 14 '14 at 15:05

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.
