Process manager provides information about running processes and option terminate them if needed. System Ninja can end non-responsive programs more effectively than the Windows task manager because rather than end the process, System Ninja simply denies it any memory forcing it to close instantly. The program also displays basic information about the installed components in your computer including the operating system, hard drive, graphics card, processor, motherboard, BIOS, network cards, etc.

System Ninja can also generate reports, view detailed information about files and even generate checksums in MD5, SHA1 and SHA256 formats. There is also an option to view System Uptime, CLR Version, Windows Serial Key and other data is available.
