It's the twenty-first century: multitasking is a way of life. Cell phones, laptops and tablets and their ever-expanding networks, apps and programs make it so we can almost always be doing at least two things at once. You send an e-mail while you're out to lunch. You call your clients while you're finishing up that presentation. You send your brother a birthday e-card while you're walking to your next appointment. Technology allows us to stay connected to the people and things we care about. It also creates a world where work and play are constantly overlapping — where creativity, productivity and recreation often go hand-in-hand. With that in mind, Windows 8.1 has been designed to bring you one operating system that can handle all of life's demands — no matter what it throws at you. Whether you're at work, at play or just looking for some inspiration, Windows 8.1 is there to deliver.
