Q: How many Microsoft help desk staff does it take to change a light bulb?
A: Four.
One to ask “What is the registration number of the light bulb?”
One to ask “Have you tried rebooting it?”
Another to ask “Have you tried re-installing it?”
And a fourth to say “It must be your hardware, the light bulb in our office works fine.”

Computers are like air conditioners. Both stop working if you open windows.
