Hello, We often get (spam-like) posts here about registry cleaners and optimization Tools. Practically none are free. They claim a lot, but are they worth the money? The Dutch PCM (Personal Computer Magazine) did a test in their April 2011 issue. They took an image of one of their editorial PC's, which was one and a half years old and never optimized. They compared a manual cleaning, using only standard Windows tools, with the results of a set of 9 tools by measuring startup time, shutdown time and speed according during the PCMark Vantage test. The results summarized below are interesting. They showed that some products actually slowed the system or increased the startup time. One program (see table below) even manages to increase both the startup and the shutdown time and slowing the system at the same time. On the positive site: they reported no problems with the system after running these tools.
