With Windows 7 Professional, your
laptop can remember your preferred printer on each network you use—no more manual switching. Setting your laptop up for a presentation is a
breeze, so you can always put your
best foot forward. And since 
Windows 7 manages power more efficiently and connects to wireless networks faster, it's easier than
ever to work on the go.

Just because you use your PC for work doesn't mean you have to sacrifice play. When it's time for a break, you'll enjoy the unbelievably realistic game graphics of DirectX 11, plus all the audio-visual goodness that comes with Windows Media Center—like the ability to watch, pause, and record live TV—and Windows Media Player.

Most programs designed for Windows XP work fine in Windows 7. For those that don't, Windows 7 Professional has a solution: 

Windows XP Mode. This free download, which works only with the
Professional, Ultimate, and
Enterprise editions of Windows 7,
can run Windows XP programs in a separate window right on your
Windows 7 desktop.

All editions of Windows 7 come with improvements to Backup
and Restore for a "set it and forget it" approach to backing up
your files and folders. With Windows 7 Professional, you can also back up files, folders, and even
drives to a network—and file encryption can help keep confidential information secure on PCs with more than one
user.

With Windows 7 Professional, you can think less about technology and more about getting things done. Performance improvements and a redesigned desktop help you get more done in
less time. It's simple to connect to domains andaccess offline files on a network even when you're not online.
