Possible to stop the current execution of commands in command prompt?

Did you try the following key combination: CTRL+C

UPDATE

For Windows 10 (cmd, PowerShell) you can use one of this:

  • Right CTRL+C
  • CTRL+Pause/Break

First use tasklist to show all running tasks. Then use taskkill /PID 1234 to kill a specific task (PID is the second column) or use taskkill /IM program.exe to kill a specific programm (all instances).

Or just use Ctrl+C to kill current running programm in current cmd window.
