Most all-in-one tools require a certain level of knowledge and so does some of the function of the ASO product. Those coming to mind would be the registry cleaner for a start (none I tested are just click and all goes well - you have to be careful always). But the memory optimizer, driver updater, system cleaner, registry optimizer all work smoothly and problem-less. The only bother is that most of those tools, if schedule, do not have a silent mode (so the GUI opens and performs the task and you need to wave the window away). I would still rate this as "good" as it covers many common tasks for a good overall optimization of your PC.

Driver Updater returns many false positives. Do not use this part of this utility. If you do make sure you set system restore point beforehand.
