Many months ago I uninstalled java v7.something.something
I see under <user>\ApplicationData\Sun directory for alternate admin and me and one other user.
There are installers going as far back as v6.
At this point I renamed them, but can I just delete \Sun totally? That'll save me 1/2 gig of space
What about registry - if any junk there? Ccleaner doesn't see anything java in registry scan.
Thanks in advance for any suggestion.
