## In order to use this, you have to 
## Create a "Scheduled Task" named "Elevated powershell.exe" to run
##    PowerShell -Command "exit"
## The scheduled task must be set to "Run with highest privileges" 
## NOTE: THIS IS A SECURITY RISK. 
##    You should at least set it to run only when you're logged on
##    I also do NOT set it to run "Hidden" so I always know.
