Ashampoo WinOptimizer is a tune-up utility for PCs and performs functions such as defragmenting your hard drive and deleting unnecessary files (like old registry settings) as well as other functions one would expect of an optimizer utility.
The newest version has an improved user interface and some new tune up tools. In testing it was found to successfully clean up a range of user and system files. However it is not as feature rich as some of its market competitors although it does have a more attractive pricing scheme. The free version is quite effective and gives a good look at the software’s functionality.
In this Ashampoo review the conclusion is that it is a solid contender in the optimize Windows space and performs its function adequately well but is not among the best in this field. For users that just want a basic PC cleaning utility this is not a bad choice with competitive pricing.
