Registry CLeaners

[Pindar]

What does the collective wisdom of the org. consider the best (hopefully free) registry cleaners? I'm looking for something that would fix runtime errors. Thank you.

AdAware 6.0 Personal is pretty good.

Then there is RegCleaner, where you do everything manually. However, its quite good, and you can edit the startup list and lots of other stuff I find handy. If you cant find it, I send it to you, as it is freeware.
