System Ninja is a simple, neat and handy system optimization tool that can improve the performance of your system by detecting and removing the junk files from it. Junk files not only consume and uselessly fill the precious disk space, but when they accumulate in huge proportions, they can also hinder and slow down the performance of the computer and cause annoying errors. System Ninja gets rid of junk files in a fast manner. Scanning for the unneeded files will take only a few minutes even on very old systems.

System Ninja is not only fast, but also quite small, neat and lightweight. It comes with a simple and intuitive interface that can be used with ease even by beginners. Despite being lightweight and easy-to-use, it provides with plenty of additional features and functions. For example, it includes a handy startup manager that lets you control which programs start at the same time with your Windows system. Eliminating the unneeded entries can improve the Windows startup time. It also includes a task manager that lets you control the running processes, and an application uninstaller that lets you remove installed programs from your computer. Last but not least, a powerful and comprehensive system information retrieval tool is also included. This tool shows thorough information about the hardware components of your system.

As you can see, System Ninja offers a lot of handy features and undeniable benefits. Since it’s also free and it bears such a cool name, it gets to be one of my favorite system cleaning tools. Its only downside is the fact that it doesn’t create a system restore point before eliminating the junk files, and this means that inexperienced users could cause harm to their systems if they use this tool carelessly. Anyway, the chances of that actually happening are very slim, almost inexistent, as this tool does a great job at properly selecting only the junk files that are truly no longer needed by the system.
