Windows 7 for You: Works the Way You Want

Speed, Reliability, and Responsiveness

Power-Saving DVD Playback

With Windows 7, your PC will use less power when playing a DVD. Windows 7 requires less processing power than previous versions of Windows and is more efficient when it spins discs.

Wake on Wireless LAN

Having your PC go into Sleep state when idle is a good way to conserve power. But what if you need to access your PC remotely? In Windows Vista, you can wake another PC in Sleep state only if it has a wired network connection. In Windows 7, you can use the Wake on Wireless LAN feature to wake the PC over a wireless network connection. Let’s say you’re using your laptop in the bedroom and want to see a photo on the PC in the kitchen. Because both are connected to your home network, it doesn’t matter if the kitchen PC is in Sleep state, because you can use Wake on Wireless LAN and view the photo. Similarly, the IT administrator in your company can wake up wirelessly connected PCs to apply software updates or perform other maintenance—and save on power costs too.

Smart Network Power

Your mobile PC may send energy to parts of your computer even when they’re not being used—such as sending power to the network adapter when you don’t have an Ethernet cable plugged in. Windows 7 automatically turns off power to the network adapter (subject to adapters and drivers supporting this feature) when the cable is disconnected and restores power when the cable is connected. IT professionals can take advantage of this feature to reduce power costs.

Power Efficiency Diagnostics

In Windows 7, we’ve updated the power configuration utility to detect problems with devices, policies, firmware, system settings, programs, and other common items where settings can reduce power effi- ciency. The information is presented in an easy-to-understand report. Although we designed this feature primarily for developers and system integrators, it may also be useful to the tech-savvy.
