On Thursday, Microsoft CEO Steve Ballmer sent employees a memo outlining changes in the company's senior leadership. Here are some excerpts from that memo:

---

"This company has always had a big vision - to help people realize their full potential. In the earliest days, it was by putting a PC on every desk and in every home. We've come farther than we could have imagined. The impact we have collectively made on the world is undeniable, and I am inspired when talented new hires say they chose Microsoft because they want to change the world - that's what we do today, and that's what we'll do tomorrow."

"About a year ago, we embarked on a new strategy to realize our vision, opening the devices and services chapter for Microsoft. We made important strides - launching Windows 8 and Surface, moving to continuous product cycles, bringing a consistent user interface to PCs, tablets, phones and Xbox - but we have much more to do.

"Going forward, our strategy will focus on creating a family of devices and services for individuals and businesses that empower people around the globe at home, at work and on the go, for the activities they value most.

"We will do this by leveraging our strengths. We have powered devices for many years through Windows PCs and Xbox. We have delivered high-value experiences through Office and other apps. And, we have enabled enterprise value through products like Windows Server and Exchange. The form of delivery shifts to a broader set of devices and services versus packaged software. The frontier of high-value scenarios we enable will march outward, but we have strengths and proven capabilities on which we will draw."

"We are rallying behind a single strategy as one company - not a collection of divisional strategies. Although we will deliver multiple devices and services to execute and monetize the strategy, the single core strategy will drive us to set shared goals for everything we do. We will see our product line holistically, not as a set of islands. We will allocate resources and build devices and services that provide compelling, integrated experiences across the many screens in our lives, with maximum return to shareholders."

"Together, we have created great products and great success, but we all want more. That means a strategy to deliver a family of devices and services that best enable people for the activities they value most and the enterprise extensions and services that are most valuable to business. A new structure to bring these to market faster. Stronger centralized services so we can be more efficient and effective. Priority focus areas, short and long term. New characteristics of how we work together. In other words, better execution and innovation through strategy and goal and discipline and engineering coherence. One Microsoft all the time.

"Across Microsoft, we are facing incredible new opportunities. As devices become further integrated into everyday life, we will have to create new and extraordinary experiences for our customers on these devices. We are going to focus on completely reinventing experiences like creating or viewing a creative document and what it means to communicate socially at home or in meetings at work. We are going to immerse people in deep entertainment experiences that let them have serious fun in ways so intense and delightful that they will blur the line between reality and fantasy. And as we develop these new experiences, we will also support our developers with the simplest ways to develop apps or cloud services and integrate with our products. We will help businesses that find themselves in a new world of ever-mounting information to manage that information through greater enterprise information assurance. We will make these high-value activities priorities in our strategy.

"Lots of change. But in all of this, many key things remains the same. Our incredible people, our spirit, our commitment, our belief in the transformative power of technology - our Microsoft technology - to make the world a better place for billions of people and millions of businesses around the world. It's why I come to work inspired every day. It's why we've evolved before, and why we're evolving now. Because we're not done."
