How to specify my own WSUS server as the download source for Windows Update instead of going to Microsoft website?

I know there is an GP located at

Local_Compu_Pol\Admin_Templ\Win_Componet\Win_Updat e\

Spedify intranet Microsoft update service location = 192.168.0.10

But remember it is for WSUS Client - Control Panel\System\Windows Update\...

Somebody wants to do the update this way

Internet Explorer -> Tools --> Windows Update

But still he want to use the WSUS instead of going to Microsoft. Is it possible?
