I have to push out workstation updates to Windows PCs. This may require reboots, since they need SP3.

I want to do this over a weekend when the users are not around, but since it will require reboots, I don't know their passwords. How do I get ZENworks 7.1 to do this?

Sorry for asking such ignorant questions.

We would like to get everyone (about 600 PCs) updated over a weekend or two and minimize user intervention.

Thank you.
