I can't run the file cmd.exe /k "...", I get the error 800a0401! I used the method set a = WScript.Createobject("WScript.Shell")

Error on line 3, character 14.

dim a
set a = WScript.CreateObject("WScript.Shell")
a.run cmd /k "@echo off && echo Hello World && pause && exit"

I tried to write a = nothing at the end of the code and replaced cmd with cmd.exe Before a I put dim a Nothing helped

    The Run() method expects a valid string which starts and ends with double quotes, this is VBScript 101. As the Documentation says - ""String value indicating the command line you want to run. You must include any parameters you want to pass to the executable file.. Commented Dec 4, 2024 at 18:18

Your syntax for calling the a.run method is incorrect.

It should be:

set a = WScript.CreateObject("WScript.Shell")
a.run "cmd /k ""@echo off && echo Hello World && pause && exit"""

The whole command needs to be within doublequotes. You can then escape the inner doublequotes by doubling them.

This is a quick flag as duplicate and move on, not the first or last to not understand basic VBScript syntax.
Uniquely, there were no quotes on the outside. I didn't find a good duplicate immediately to really bring the point across. Your comment about the documentation is probably going over OP's head, I assume they just want to get things to work and don't even know what a "string value" is, let alone how its escaping rules work. You can just downvote this answer if you disagree.
In which case, not the place to ask.
