I ran the Registry Cleaner and it found a lot of entries, but would not delete several, and I had to manually delete them.
I did the same (upgraded java to version 7), ran the registry cleaner and all found entries were deleted without any problem.
I must specify that I uninstalled the previous java version (6 update 26) before running the registry cleaner.
Perhaps that is the solution.
I installed JRE 7, but did not uninstall JRE 6 update 26 first.
I uninstalled JRE 6 update 26 afterwards, and then found the various leftover registry entries.
Even so, I would like to believe the registry cleaner would delete those entries.
By the way, the registry cleaner did give any errors, it simply did not remove the entries, even though it cleared them from the list. Running another scan, those same entries reappeared, until I manually deleted them.
