临时禁止代理：
Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' ProxyEnable -value 0
临时启用代理：
Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' ProxyEnable -value 1


彻底干掉代理：
Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' ProxyEnable -value 0
$proxyServer = ""
$registryPath = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
Set-ItemProperty -Path $registryPath -Name ProxyServer -Value $proxyServer
