Put your questions to Bill Gates

Mr Gates founded Microsoft in 1975 with his childhood friend Paul Allen

Bill Gates is to answer your questions at the Consumer Electronics Show in Las Vegas.

The software supremo and co-founder of Microsoft is preparing to end his day to day involvement with one of the largest and most powerful companies in the world.

Mr Gates will remain as chairman and will continue to advise on key development projects.

As he gets ready to change his role, one of the most important men in technology over the last three decades has invited readers of the BBC News website to send him questions about his life and career.

Perhaps you have always wanted to know what the inspiration was behind Windows. Maybe you want to know what it is like being one of the world's richest men. Or maybe you are more interested in the philanthropic career he has planned after he steps down.

Thank you for your questions. A selection of the best, and the answers will be posted on the website and broadcast on BBC news.
