Having Fun at the Command Line

We are owned and operated by refugees from the corporate wars who wanted to have a little more control over our results and fun in our lives. Our primary products are command processors, tools that assist the user in working at the command line (the C:\> prompt) and with batch files. We currently offer products for Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, and Windows Server 2022.

We have the flexibility to meet your needs quickly and configure our products the way you want them. Founded and run by technical experts, we have great technical depth and a proven track record. We offer powerful, solid products you can rely on every day, as hundreds of thousands of our worldwide customers already do.

For more information on the company or our products, or for any other matter, please feel free to contact us via email or on the forums. Don't forget to browse the remainder of this site and to visit our support forums.
