Selecting One or Multiple Conditions of Which ALL Must Match for an Action to Execute

Checking the "ALL" checkbox allows to select one or multiple Conditions, ALL of which must match for an Action to effectively execute.  

Good Example:

[Client has 2 GB of memory] and [Client has 2 GB of free disk space]

Bad Example:

[Client is laptop] and [Client is desktop]

A client cannot be both of type laptop and desktop - such a combination of Conditions should be selected in the "At least ONE" list of Conditions.
