As Torgeir says, a RunAs wrapper could be used.

The other alternative is to give your users admin rights to the machines.
Or, you could use a computer startup script within Active Directory if you
are using it.
One issue, though. How are you going to stop the patch setup running again
and again, even when the patch is installed?
I know you need to get this patch deployed now, but SUS really is the best
all round solution for future patches. SUS is available now, WUS will be
even better when it's released.
Another alternative is the excellent GFI LANguard Network Security Scanner,
which can push patches over the network. There's a 60-day eval version
which then reverts to the Freeware version, which in itself is worth having
just for network scanning. See
www.gfi.com. It's fairly intuitive, but I
will add that clicking Tools | Security Scanner is the way you select the
results window, from which you can right-click the a computer having
completed a scan.
Hope this helps
