Many companies aspire to change the world. But very few have all the elements required: talent, resources and perseverance. Microsoft has proven that it has all three in abundance.

This is a critical time for the industry and for Microsoft. Make no mistake, we are headed for greater places — as technology evolves and we evolve with and ahead of it. Our job is to ensure that Microsoft thrives in a mobile and cloud-first world.

The opportunity ahead for Microsoft is vast, but to seize it, we must focus clearly, move faster and continue to transform. A big part of my job is to accelerate our ability to bring innovative products to our customers more quickly.

Our mission of empowering every person and every organization on the planet to achieve more is really a look back to the very creation of Microsoft.

A lot of people are joking about the Windows 10 error message that says 'Something Happened'. Well, that's not on me. My original idea was to not have any errors at all, and for the operating system to be called Windows RT ME One.

Our ambitions are bold and so must be our desire to change and evolve our culture.

This is a software-powered world.
