From me this new version gets (unlike so many other review) 5 stars. I have on my PC Win 8.1 and all the tools that provide the TuneUp available to optimize the system, operate it properly (without even a single malfunction). After PC optimization with this program my laptop was noticeably faster. I had previously been the TuneUp 2010 to another PC and was just as happy as now with the 2014ner version and can therefore happy to recommend.
