You can not easily mirror Windows Update, but you can cache it and have
clients redirected to the cache.
The host names used by Windows Update must be accessible by the clients.
The host names does not really need to point to Microsoft, but may point
If you want your clients to go to another hostname then there is a product
you can buy from Microsoft for setting up a "Windows Update" style
distribution server. Don't remember what it is called but you can find it
in another thread about Windows Update some weeks ago..

The difference is that the Windows Update function knows it's servers, so
even if you request a specific server in the browser the Windows Update
will try to use the server names it thinks it should have, so for this to
work the client needs to know that for the Windows Update domains it
should talk to your accelerator, not Microsoft. This you can configure in
your internal DNS to have the Microsoft Update domains redirected to your
accelerator, just make sure your Squid is using a real DNS without this
