What are these reg entries?

Before CCleaner came out I used to use a reg cleaner called TweakNow, which I liked because, like CCleaner, it wasn't particularly thorough but it was extremely safe. When CCleaner came out though its issues scanner seemed to find everything that Tweaknow would find.

Well I've just stumbled across TweakNow again and its changed a bit and finds some entries that I'm not sure what they are, though they all seem similar. Anyone tell me what the entries in the attached screenshot relate to? (I'm not bothered about the first two)

Just had a little look around and all I can come up with at the moment for the pkmsa entries are that they may be to do with routers, do you have one?

As for the second lot see here
