Installing updates using WSUS how

I've installed WSUS on my server and have approved a couple of updates....
and the updates have been published to my workstations.... BUT
I have notice that when Install the updates on the workstations they usually
requires a restart.... But when the users are using the workstations I can't
just restart. But if I don't the workstations get unstable and the users
might expirience unexpected program errors.

Can't you get the installations to happen at shutdown or at bootup like a
RIS installation for an example....

This would be much more efficient....

Any ideas ?

How do you do at your location?
