Server: Update Management
The Update Management base policy lets you specify when product updates become available on your network. This ensures that your computers don’t start updating until a time that suits you.
Some options are only for Windows servers. The columns on the right of the page show you which server type each option is for.
Enable Scheduled Updates and select the day and time when you want product updates to become available.
Remember that if computers aren’t on, they won’t get the update until the next time they start.
