Has a built-in defragger and a duplicate file finder.
Has a built-in srong uninstaller.
Find and remove malware.
Has the ability to backup your registry and/or create a system restore point.
Has a schedule that allows you to set automatic cleaning to happen at X time every day, every three days, every week, or every two weeks.
Allows users to see what is going to be cleaned prior to the program actually doing the cleaning, giving users the ability to manually select not to clean specific things. In other words, a scan is conducted and you are shown the scan results prior to actual cleaning.
Comes with eleven different 'skins' you can pick from.
Through 'Settings' you can control what each cleaner module cleans (e.g. what type of registry entries to clean, what type of junk files to clean, to clean internet history, cache, and/or cookies, etc.).
However, the control is at a high level. For example, you cannot tell the program to only clean cookies from Chrome and not all browsers; it will either clean cookies from all browsers or none at all. Does not specify what browsers it works with. As per my tests, at least Internet Explorer, Firefox, Chrome, and Opera are supported.
When minimized, it goes to the system tray as opposed to appearing in the taskbar. This is extremely annoying because once it goes to the system tray, users are highly likely to forget the program is still running. There is no option to change this behavior.
I'm not a registry expert nor am I a computer programmer, so my level of analysis in terms of being able to understand what is safe to clean and what is not is questionable.
That said, using a cleaner program to clean junk files and temporary internet files is a better bet. In fact, I encourage users to have at least one program that cleans temporary internet files (e.g. history, cache, and cookies). A junk file cleaner isn't needed as much but is good to have, although you should keep in mind even a junk file cleaner can screw up your computer if it is badly coded (e.g. delete a system file thinking it is junk). However, that risk of a junk cleaner is much lower than a registry cleaner.
This software must be a pile of steaming crap! I would never buy or even install software that won't let you try to fix SOME of the errors it finds. There's a good reason why they won't let you do it, when it scans your computer it will show tons of FAKE errors that are not really in your computer.
I would look for better software. Good software will let you try it out for like thirty days or more and if it's good, the product will sell itself.
