I use TuneUp since 2008. This is an excellent maintenance software. The interface of the 2012 version is a bit complex and offers more features than the version I owned (2008). Among the new features, the software gives priority to certain programs. On Windows 7 pro 64 bit, it works without problem in compatibility mode, and is much faster than the integrated maintenance center on my PC. I had a small problem on the key the letter Q having been interchanged with a service center O. answered me very kindly 48h00. Apart from this against the meantime, I recommend this software.
