batch script if user press Ctrl+C do a command before exiting

Question

I wrote a script which is doing net use at the beginning and net use /DELETE at the end.

But if user decides to press Ctrl + C and exits the script, I need to do a net use /DELETE.

Is that possible? I can't find anything on google.

Sure, simply execute most of your script in a new CMD session:

@echo off
if "%~1" neq "_start_" (
  net use ...
  cmd /c "%~f0" _start_ %*
  net use /delete ...
  exit /b
)
shift /1
REM rest of script goes here

As long as your console window remains open, the net use /delete command will always fire after the inner cmd session closes. It could close because of normal run, user presses Ctrl-C, or fatal error - the final net use \delete will still fire.
