Cookies and registry

I would love to drop CCleaner and use this. Except.
I can't import my protected cookie list from CCleaner (Privazer does this nicely) and the one other feature I use from CCleaner is the registry cleaner, since it's proven for years to be conservative and safe for the registry. Still, thank you very much for developing this.

No files, tests, or entry points are named. First clarify whether the goal is CCleaner protected-cookie-list import, registry cleaning, or both, then locate the relevant application areas and define separate completion criteria for each feature.
