On your Local Network, you may have several client PCs. Organizing them to groups, will allow you to select a group of PCs and execute remote tasks to PCs of this group only.
For example you may want to install software or shutdown all PCs in Office 1 group but not those in Office 2 group (see Remote Commands - Actions) .
At any time you may create new groups, rename existing ones, or move PCs from one group to another.
