Since the release of this tool, I have seen a very repeated bug that is getting very annoying. Normally if you disable an entry using the tool and then update an app the normal expected behavior should be that entry remain in the way it is. But that doesn't happen apps are set to enable autoruns even if they don't ask the user within the installer so you should think the entry is gonna get rewritten and the disable rule is gonna be lost but in fact what happens is that the rule is duplicated in CCleaner tool and you have to disable it another time but the weirdest stuff comes if you dice to erase the key, it will be wiped out but also the duplicates. So seems that the issue is not on Windows Registry but on CCleaner.
Note: attach files system is not working!
