I want to make auto login to system proxy.

I can set the proxy in registry:

```
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

```

Keys values:

```
ProxyEnable = 1
ProxyServer = IP:PORT

```

but I don't want the user of my application to enter login and password in his browser, I don't want him to click Login, I want to do this automatic.

I have tried to set ProxyServer key to:

```
ProxyServer = username:password@IP:PORT

```

But this doesn't work.

Any ideas?
