Nir Cmd is a small utility that lets you run command lines to do useful tasks in your operating system without needing to show any user interface.
It is very easy to use. Just run Nir Cmd and to the corresponding command line you can add or remove values, registry keys, write values in the INI file, connect to a virtual private network (VPN), restart or shut down your PC, create shortcuts to chosen files, modify file parameters, configure the screen, control the music volume, open the CD or DVD tray, etc.
With Nir Cmd you can do all these tasks much more quickly than the Windows operating system itself, without needing to open multiple windows.
