System Ninja is a program that looks cute, but means serious business when it comes to performance. It's a utility for system optimization and cleaning, a very useful tool for people who have a messy hard drive and a serious slowing down of their OS performance.

It's core functionality is advanced cleaning procedure. The program lets you scan the system and find obsolete or simply junk files, as well as elements of other programs that can be erased without harm to anything. This included browser history and cookies, invalid file paths, as well as a great selection of programs you have installed that can be deleted without a trace. System Ninja is a good and thorough uninstaller, it frees a lot of space you thought was occupied by something important. I tried to find disadvantages in core functionality, but found none. it's all clean and fast.

But deleting other programs isn't the only thing System Ninja can do, or it would simply be another generic uninstaller. It can also control system processes. You are able to optimize your system by redirecting processed, turning some of them of and on, delete the core system apps you think you don't need. There's even the option to analyze your hardware to determine what you can do to upgrade or enhance it.

All in all, I liked System Ninja. It's nothing too special, but being small and cool is a good choice. This program really is like a ninja - silent and fast at what it does. Moreover, the program itself is compatible with various extensions that add to basic functionality, making it a more complex tool. So, if you need a quick and safe way to optimize your system by taking out the trash, try it.

It should be a little fast. Takes too much time and also scans C: drive even if it is not selected.
