    I think you need to check
    (1) if you're using express edition. If so, you need standard or enterprise edition. 
    (2) If set processor affinity mask for all processors

    The setup is to automatically use 4 CPUs if required.  The report you're looking at has nothing to do with how many CPUs are used.  The "1" in that report under the large blue block is just saying that's the first worst query insofar as CPU usage.  It may not actually be a problem depending on what the query is doing.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
