How to kill all cmd windows except the current one?

Question

cmd/bat

I am using .bat with commands:

@echo off
     taskkill / IM cmd.exe
     echo "Тест"

This command closes all open cmd windows, including the current ones. How can I prevent this and not close the current window?

I tried to kill it like this: I

taskkill /F /IM run.bat

run these 2 run.bat files in different directories
