I am using Tune Up since 2009. At that time from a PC Magazine, for free. Meanwhile I did with Windows 2000, XP and Win 7 so my experiences and have come to the conclusion that it can not do without this tool. One must, however, take the time to sift through this tool to view it in detail can. Of particular importance are "TuneUp System Control and up disk space." For this purpose, it must not be the newest tool, the TuneUp 2011, efficiently and quickly. There might be better tools for the same tasks, but what helps me limitless speed when subsequently prepared empty folders are missing that were created by me and which was not recognized by the cleanup tool. In my view, can not do without PC users to TuneUp.
