We have servers in our data center pointing to an internal server for updates. I have the update properties set to update dats, engines, and program updates, service packs. I am concerned that some of the engine or service pack updates will require a reboot following the upgrades. These are production servers with defined change windows so I can't have them rebooting without change notification. My question is should I disable the engine and patch updates and only select dat updates so there will be no danger of a reboot or will the reboot always be suppressed?
