KiXtart is a closed source free-format scripting language for Windows. It is described as a logon script processor and enhanced batch scripting language by the official website. Its name is a portmanteau of "kick start". Overview
KiXtart is developed by Ruud van Velsen of Microsoft Netherlands. It is now provided as careware. Development started in 1991 to provide login scripting for the Microsoft LAN Manager environment. It has rich built-in functionality for easy scripting and provides access to ADSI, ADO, WMI, etc. The language can be used to display information, set environment variables, start programs, connect to network drives, read or edit the registry, change the current drive and directory, and much more.
