Prox on, Prox off: Windows Proxy On, Windows Proxy Off with PowerShell

These four files will give you the ability to switch between
having a proxy server set in Windows and not having one set 
without having to navigate a bunch of windows each time. 

Because Windows won't allow a PowerShell script to execute by 
default the scripts are called using batch files so the execution 
policy can be altered before and after calling the script.
