.SYNOPSIS
  Keeps you productive by spoofing activity to prevent GPO idle timeouts, RDP disconnects, sleep, etc.

.Description
  This script creates a Scheduled Task that runs at login which uses Kernel SetThreadExecutionState to prevent GPOs
  from disconnecting your RDP session. Will also prevent sleeping/screensavers/display timeouts

  See the example below for a one liner that will download and execute this script directly from GitHub!
