Unlock all your System Preferences
This i found on a google search, not my idea
Step 1: What to do
Check you System Preferences (SP from not on), usually locked at school or work, make sure that yours are locked, if not then your done.
Do a Spot light search for "system preferences"
Drag and drop (copy) SP to your desktop or where ever you want it from the Spotlight search
