Microsoft chief executive Steve Ballmer said the company is being restructured in what is the first major overhaul for five years.
The software company will be streamlined around devices such as phones, games consoles, and services.
He said Microsoft will be able to react faster with new products and services.
The move comes amid a decline in demands for personal computers, as consumers turn to tablets and other mobile devices.
