I, for one, do not understand exactly what your question is. Perhaps one of the other members will be able to understand it. I mean no disrespect, but if you would break up your post into sentences with the correct punctuation marks, it would be easier to understand.

This will rid you of SP1 temp files if not already shown above.

I do not recommend third party cleaners.
You might remove something you need and the result can be reinstalling Windows.
