It’s possible to write a task sequence variable but not the Windows Environment Variables. But you can write a simple wsf file and use the in-built registry write function.

<job id=" Z_Filename.wsf ">

<script language="VBScript" src="ZTIUtility.vbs"/>

<script language="VBScript">

oShell.RegWrite "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\MDTPath", oEnvironment.Item("DeployRoot"), "REG_SZ"

oLogging.CreateEntry "Registry Value Successful.", LogTypeInfo

</script>

</job>

Save the file Z_Filename.wsf to scripts folder

From the task sequence, just create a step run command cscript.exe "%SCRIPTROOT%\Z_Filename.wsf"

clip_image001

clip_image003

Above script creates an system variable called MDTPath and set the value to the oEnvironment.Item("DeployRoot") which would be \\servername\sharename$ in this case.
