Of course, the program functions has also there which are absolutely unnecessary (z. B. Turbo mode or live mode) or even dangerous (such. As cleaning the registry). For 1 star deduction.
By contrast, other tools such as the general optimization of some PC settings, clean up Auto Start, defragmentation, Large files are found, or delete, PC clean up, etc. for me personally very useful and helpful.
For all cowards: It is also a rescue center there! All changes can be undone!
