Microsoft CEO Steve Ballmer positioned Windows 7 as an operating system that can drive new and innovative products, as the company tries to fend off competition from tablet computers based on software from Google and Apple.
"Only the imagination limits what can be done with Windows PCs today," Ballmer said in his speech at the start of the Consumer Electronics Show in Las Vegas. "You can write on them, draw on them, hang them on the wall, touch them, use wireless keyboards, play a game and much, much more," he said.

Mike Angiulo, a Microsoft general manager, showed off several upcoming Windows 7 PCs with unusual designs. One of them, from Acer, had two large touch-screens connected together like a notebook. Touching all 10 fingers on the bottom screen turned that screen into a virtual keyboard for typing.
He also showed a Samsung laptop with a screen that can slide closed over the top of the keyboard. When the device is closed the screen faces out so it can be used as a tablet. And he showed an Asus tablet PC that has a separate wireless keyboard and a particularly bright screen that he said is easy to view from almost any angle.
All the PCs were running Windows 7 and will be available in the next few months, Ballmer said. "They're on the leading edge of new devices that offer it all," he said.
Microsoft is facing new threats from Apple with its popular iPad and from tablets based on Google's Android operating system. While Windows 7 is used on some tablets, those available have not captured the imagination like those from Microsoft's rivals.
Ballmer also told the audience how the next version of Windows, which has yet to be officially named, will be available for the Arm chip architecture. Historically, Windows has been based on the x86 architecture used by Intel and AMD. Arm chips typically allow for better battery life and are used in devices like mobile phones and tablets.
Transitioning Windows to Arm will be a major undertaking, and to prove the work is already underway Angiulo showed some early Windows code running on stripped-down Arm-based hardware. He showed Windows running on a Qualcomm Snapdragon chip as well as a chip from Texas Instruments. "This is Windows running natively on Arm," he said.
