I wasn't sure on where to post this, so I'm posting here. Mods, please move this to the right section.
I accidentally set a file format (.jar) to be opened always with the command prompt, now I cannot change it back (the checkbox for "always open with" is disabled).
What I wanted was to leave the prompt in the Open With tab when I right click the file, but it still won't show up there, and I cannot change my .jar back to "Open with javaw.exe".
Is there any place in the Control Panel where I can change this back?
