Microsoft's new Windows 7 operating system will be available in October, and the company officials say the system will give more more functionality through form.

Among the features are desktop backgrounds that change on their own, a program called "Aero Peek" that lets nonactive screen windows turn transparent and glass and increased ability to see documents side by side.

"It's kind of the perfect combination of beauty and brains," says Latika Kirtane of Microsoft. "So we have this aesthetic look that's a beautiful design but we've also really thought about increasing the user's efficiency on the machine. So for example, Windows 7 jumplists really help you access the documents you find yourself looking at often. Windows Aero Shake is an easy way for
you to clear your desktop off and really focus on one window at a
time. Connecting laptops is one of the scenarios Window 7 really
encourages and removes some of the hinderance of home networking with home groups."

It's even designed to easily pull up content on one computer, like a
song and have it play out through another.

PC users who are still a bit traumatized by their last upgrade to Windows Vista need not worry, say some experts, and that the transition to Windows 7 will go smoother.

"It works in the ways that you'd want it to. Microsoft really listened to their customers and decided not to overpromise and underdeliver," says Lance Ulanoff of PC Magazine. "So there's smart things that you might not notice, like everything that worked on Vista will work on Windows 7. Believe me, that wasn't the case with Vista."

Windows 7 hits shelves on October 22. There will be three versions - Home Premium, Professional and Ultimate - which range from $120 to $320, depending on the version and whether PC users upgrade or buy the full package.

Pre-orders of Windows 7 through July 11 are half-off. Those who buy a PC today with Vista will get a free upgrade.

The upgrade advisor at Microsoft.com will say which models can run Windows 7.
