does windows update support resuming?

does windows update support resuming ? ie: if i shut down system while downloading a large update like SP1, can it resume download the next time from the point it stopped at it ?

Thank you.

If it was being downloaded by the Windows Update service, then it is being downloaded via the BITS service, which supports resuming (it's the reason the service was created - to trickle down Windows Updates to people with slow/intermittent connectivity).
