The windows

A woman customer called the Canon help desk because she had a problem with her printer.
Tech Support: Are you running it under windows ? 
Customer: No, my desk is next to the door, but that is a good point.  The man sitting next to me is by
a window, and his printer is working fine !

Email Joke

Tech Support: How may I help you ?
Customer: I’m writing my first email.
Tech Support: OK, and what seems to be the problem ?
Customer: Well, I have the letter ‘a’ in the address, but how do I get the little circle around it.
