Question : Deploying SP3 for XP via WSUS 2.0

When applying the SP3 via WSUS to client machines there is a Automatic Shutdown once the patch is applied, which is currently set to 5 minutes is there a way to amend this behaviour?

All Other Service packs and updates do not have this issue as Via GPO we have do not automatically restart after updates are applied enabled.
