Benchmark Report of 133 Windows Optimization Software Products These tests were performed in March 2015 Introduction Macecraft Software has published four registry cleaner product comparison studies which have attempted to answer questions about the quality of different registry cleaning products as well as what kind of effects they can have to your system. The first study dates back to 2009 and was entitled Registry Cleaner Review and Performance Comparison Study and a follow-up to it was released later in the same year. It was Macecraft Software’s In-Depth Review of 31 The Most Popular Registry Cleaner Products study. Then, in 2010, a Comparison of 176 Registry Cleaner Products study was published. The most recent study was released on September of 2013 which focused on whether or not running a registry cleaner software results in changes to system benchmark scores. That study was entitled the Registry Cleaner Benchmark Study. This time though, we looked to make waves! This was an exciting study that could really focus on what various software products were doing to our computers. In this study, 133 products were tested. The inclusion process was simple and straightforward: few software download sites were manually scanned for any products claiming to make your computer faster by cleaning it or by fixing system errors. In addition, Google was also used to find such products and the 133 products are all the products that were found. The majority of them are considered to be popular and high-ranking among consumers.
