This question is a follow-up in response to this question: https://stackoverflow.com/questions/7235228/java-jar-open-with-windows-explorer-continually-spawns-explorer-processes. I have the same problem and now wish to not know why it happens but rather how to make it stop!
Apparently, sometime in the past I changed the extension of .JAR files on my computer to windows explorer. I do not know why as I know to just change the extension to .zip. It's possible that didn't work for some reason and I acted stupid. Regardless, now I seem to be suffering from a permanent "glitch" in Windows 7. Basically, windows 7 doesn't allow things to be reassociated once they have been associated with windows explorer (as then they are just folders I guess?). Perhaps that's why.
I'd really like for my JAR files to stop spawning 967 windows explorer entities and literally bogging my computer down to the point of almost crashing every time I forget to right click and select "open with".
I did find a potential fix within this thread: https://social.technet.microsoft.com/Forums/windows/en-US/9237ca68-645c-4718-9a51-24788f312c4b/windows-7-hangs-when-opening-a-file-with-explorerexe?forum=w7itproperf
My problem is that I have no clue what this "registry editor" is (I mean I have an inkling what they mean but don't know what program they refer to) and I do not know where to find this folder they refer to.
If possible, I would prefer a very simple explanation of what folder to navigate to and delete to reset my broken JAR file association without deleting or resetting any other file associations. I'd rather not have to reinstall windows or anything like that. I know this isn't a programming question per se, but this is a pretty serious problem for me and I'd like it fixed.
