Why Microsoft redesigned Windows
New Windows chief Julie Larson-Green explains why the company felt the need to rethink the basic interface of its popular operating system.
Windows 8 has its fans and foes, but Microsoft felt the time was ripe for a new look and feel for a product used by more than 1.2 billion people.
Julie Larson-Green, the new head of Windows product development, recently spoke with MIT Technology Review about the reasons behind the major changes in the latest version of Windows.
Touting the new Windows 8 Start screen, Larson-Green said that in the past Windows users worked at a desktop with a monitor. In her view, people typically launched one window, put it away, and then launched another window. But in Windows 8, all the apps and windows you might want to launch are visible through Live Tiles.
It's no secret that Windows 8 is designed with touch screens in mind. Larson-Green sees that as simply a "natural way to interact." After using a touch-screen device, even people still using the mouse and keyboard on a regular desktop may find themselves reaching out to the screen to try to move something with their finger.
And touch screens are the future, in her opinion. Though she concedes that there will always be some PCs without touch screens, she believes the majority will be touch-enabled.
"We're seeing that the computers with touch are the fastest-selling right now," she said. "I can't imagine a computer without touch anymore. Once you've experienced it, it's really hard to go back."
Windows 8 has been criticized for trying to be all things to all people. The Start screen environment is geared more for touch-screen devices, but the familiar desktop is still easier to use with mouse and keyboard.
Microsoft made a purposeful choice to offer both environments in the new OS, according to Larson-Green. A mouse will always be more precise than your finger, while a physical keyboard will always be easier to use than an on-screen version, she said. But she feels that eventually people get more comfortable with this new way of working.
"We didn't want you to have to make a choice," she said. "Some people have said that it's jarring, but over time we don't hear that. It's just getting used to something that's different."
