KiXtart is a Windows logon-script processor and enhanced batch scripting language. To run a script, save it as a text file such as hello.kix and invoke the interpreter with kix32 hello.kix. It was built for Windows networking and is now best treated as legacy technology: check compatibility on the exact Windows clients and servers you use before deploying it.
What KiXtart is and why administrators used it
The KiXtart 2010 User Manual describes KiXtart as a logon-script processor and enhanced batch scripting language for Windows networking environments. It combines compact commands with variables, runtime macros, functions, structured control flow, network operations and Registry access. That made it useful for automating tasks when users signed in to a Windows domain.

A single logon script could identify a user or workstation, display information, set environment variables, connect network drives, launch programs and read or edit the Registry. A Microsoft Knowledge Base summary describes these as typical KiXtart tasks: Microsoft’s KiXtart task summary.

How to run a .KIX script
KiXtart’s interpreter is Kix32.exe. The manual documents starting it from a command prompt; when a script is specified, provide its filename after the interpreter. The following is an instructional example, not a claim of testing on a current Windows version.
#1 Best Overall
- Create a plain-text file named
hello.kixcontaining:? "Hello, @USERID"
EXIT 0 - Open a command prompt in the directory containing the interpreter and script, or use paths appropriate to your installation.
- Run
kix32 hello.kix. The@USERIDmacro is expanded at runtime for the logged-on user;EXIT 0ends the script with a success status.
The manual says that if KiXtart starts without a script name, it looks for a user-specific script and then a default script. Those fallback conventions are useful to know in older deployments, but an explicit script argument makes manual runs easier to understand.
KiXtart syntax basics
KiXtart source is free-format. Its beginner building blocks are variables, @ macros, conditional branches, reusable functions and commands such as RUN.
Rank #2
Variables and macros
Variables begin with a dollar sign. For example, $name = "Ada" assigns a text value. Macros begin with @ and provide runtime information; @USERID represents the logged-on user in the example above. A variable holds a value your script assigns, while a macro supplies information from the KiXtart runtime.

Use IF ... ELSE ... ENDIF when a decision has two branches. The condition belongs after IF; the commands for the alternative branch follow ELSE. Keep the block clearly delimited with ENDIF so later maintenance does not depend on visual indentation alone.
SELECT and CASE
For several alternatives, SELECT ... CASE ... ENDSELECT expresses the branching structure more clearly than a long series of nested conditions. Each CASE corresponds to a value or condition the script is intended to handle.
Functions, CALL and RETURN
User-defined functions let a script reuse a sequence of operations rather than duplicating it. The reference documents CALL and RETURN for invoking and leaving reusable routines. Keep functions focused, especially in logon scripts that other administrators may need to diagnose.
RUN
RUN "command" starts an external command. On a current Windows client, whether that command resolves and whether it can run successfully depends on the environment, executable path, user permissions and applicable security controls. Do not assume a command available on one workstation will be available to every user.
Checking for errors
The KiXtart manual recommends checking @ERROR and @SERROR after commands and functions. A zero value for @ERROR means the preceding operation succeeded; a nonzero value indicates that the script should not silently assume success.
- Check immediately after operations involving network resources, files, the Registry or external programs.
- For nonzero results, branch to an appropriate recovery or reporting path rather than proceeding as if the operation worked.
- Use the error information to make failures diagnosable, especially in scripts that run automatically at logon.
Using KiXtart in a Windows logon process
Windows Group Policy provides four script events: computer startup, computer shutdown, user logon and user logoff. Microsoft’s guidance explains that administrators can associate one or more scripts with these events and provide parameters: Group Policy scripts.
KiXtart can be part of a logon workflow when the client has the interpreter available. Older deployments commonly use a logon-script entry or a batch wrapper that calls Kix32.exe. Group Policy can assign the event, but it does not itself supply the KiXtart interpreter: the client needs access to the executable and script, and they must run with suitable permissions.
Is KiXtart still used on Windows?
KiXtart remains relevant as maintenance knowledge for older Windows-network environments that still depend on existing scripts. However, the KiXtart 2010 manual and community documentation cover legacy Windows generations; they do not establish a current support guarantee for Windows 10, Windows 11 or current Windows Server releases. Treat compatibility as something to verify, not assume.
- Test the interpreter, script paths, commands, network access and Registry operations on the specific client and server versions in scope.
- Check execution permissions and security policy, especially for scripts that launch programs or alter system settings.
- For a new environment, assess whether maintaining or migrating the automation is more appropriate. Compare interpreter availability, maintainability, Registry and network features, error handling, security, logging, Group Policy integration and current vendor support.
KiXtart’s historical strength was compact logon automation. The sources available here do not establish a current support comparison with alternatives, so choose a replacement only after checking current documentation for the target platform and mapping the existing script’s behavior.
