RegistryKey registryKey = Registry.ClassesRoot.OpenSubKey(key, false);
// get default browser path
return ((string)registryKey.GetValue(null, null)).Split('"')[1];
}

private void button1_Click(object sender, EventArgs e)
{
string url = "www.google.com";
Process p = new Process();
p.StartInfo.FileName = GetDefaultBrowserPath();
