Does cleaners speed up system?
I also happen to use a "cleaner" when I notice there are "unwanted entries" in my registry. Mainly to remove the "trash" when allready knowing there ARE unwanted entries (or suspect). Still I dont really see an improvement of the speed or responds.
As asked above, - I wonder if there are BENCHMARKS proving the reall benefit of a registry cleaning. Though, with these cleaners or "built in accessories", there is a positive and at times security issue, in deleting temporary files, cookies and a disk defrag at times (some skip defrag, because it's too slow. And sure it is, if seldom run).
