I’m currently working in a company where I have to set up a proxy to connect my laptop to the Internet. Because I'm fed up to enable it each morning and disable it each evening, I made two Powershell scripts to do these operations :

EnableProxy.ps1 :

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' 
-name ProxyEnable -value 1

DisableProxy.ps1 :

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' 
-name ProxyEnable -value 0 

Et voilà !

Hope this helps Winking smile
