Clients Can Update Components but not Upgrade the Client Program or Deploy Hot Fixes Parent topic

This option allows component updates to proceed but prevents hot fix deployment and OfficeScan client upgrade.
If you do not select this option, all clients simultaneously connect to the server to upgrade or install a hot fix. This may significantly affect server performance if you have a large number of clients. If you select this option, plan how to minimize the impact of OfficeScan client upgrade or hot fix deployment on the server and then execute your plan.
