Managing Proxy Settings with PowerShell

I find myself changing proxy settings often on my laptop between various environments (Home, Production and Test). Generally this is no big deal. But today, I found myself switching multiple times as I was testing ISA and realized that PowerShell can easily take care of this.

At some point, I will wrap this into a GUI but for now, here is the script.

Note: I am using Jeff Hick's Test-RegistryItem.Enjoy!
function Set-Proxy {          
[cmdletbinding()]
Param (
[Parameter(Position=0,Mandatory=$True,
HelpMessage="Enter either `"Home`", `"Production`" or `"Test`".")]
[ValidateNotNullOrEmpty()]
[ValidateSet("Home", "Production", "Test")]
[String]$Location
)

$path = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
$url = "http://autoconf.FatBeard.com/proxy.pac"

switch ($location)
{
"Home" {
Set-ItemProperty -Path $path -Name ProxyEnable -Value 0
if (Test-RegistryItem -Path $path -Property ProxyServer) {
Remove-ItemProperty -Path $path -Name ProxyServer
}
if (Test-RegistryItem -Path $path -Property AutoConfigURL) {
Remove-ItemProperty -Path $path -Name AutoConfigURL
}
}
"Production" {
Set-ItemProperty -Path $path -Name ProxyEnable -Value 0
Set-ItemProperty -Path $path -Name AutoConfigURL -Value $url
}
"Test" {
Set-ItemProperty -Path $path -Name ProxyEnable -Value 1
Set-ItemProperty -Path $path -Name ProxyServer -Value "TestProxy-vt01:8080"
if (Test-RegistryItem -Path $path -Property AutoConfigURL) {
Remove-ItemProperty -Path $path -Name AutoConfigURL
}
}
}
}
Enjoy!

Excellent. I have had a simple enable and disable proxy script but this is a nice addition.
