" I find RogueKiller is superior to CCleaner for getting rid of registry issues."

What 'registry issues' would those be? And the two programs have completely different aims AFAIK. Bizarre statement...

Yeah, hleveque, Mark Russinovich addressed that, he reckoned NOT necessary to run registry cleaners / optimisers. I think this Roguekiller is just looking at autorun locations and installed services etc, so not really a registry cleaner as such, more general anti-malware
