LONDON, England (AP) -- Proclaiming himself "humbled and delighted," Microsoft founder Bill Gates has received an honorary knighthood from Queen Elizabeth II.

The accolade allows the recipient to use "KBE" after his name, but not "Sir" in front of it.

One of the world's richest men, Gates, 49, was being honored in a private ceremony at Buckingham Palace for his charitable activities around the world and his contribution to high-tech enterprise in Britain.
