The targeting items applied to a preference item are evaluated as a logical expression. A targeting collection allows you create a parenthetical grouping within that expression. You can nest one targeting collection within another to create more complex logical expressions.
A targeting collection allows a preference item to be applied to computers or users only if the collection of targeting items specified results in a value of true. If Is Not is selected, it allows the preference item to be applied only if the collection of targeting items specified results in a value of false.
If you want to restrict the scope of multiple preference items with a complex set of targeting items, you can simplify configuration by using an environment variable. For example, create an Environment Variable preference item that generates a new environment variable with a value of 1, and apply the targeting items to it. To apply the same targeting to other preference items, add an Environment Variable targeting item to those preference items, and configure it to require a value of 1 for the variable that you created using an Environment Variable preference item.
To reposition a targeting item within the list of targeting items that you have applied to a preference item, either drag the targeting item to a new position, or select the targeting item and then click the Move Up arrow or Move Down arrow.
Preference items are available only in domain-based GPOs.
