The new Reset feature, which restores the PC to factory-fresh condition, helps eliminate one of the biggest issues with laptops--data left on a laptop after it's sold or donated.

3G/4G Monitoring

Microsoft also showcased a new control panel for monitoring your laptop's (or other device's) 3G or 4G data plan--without using up your minutes if you happen to be roaming.

Device Interactivity and Connectivity

Other forward-thinking features built into the operating system include "tap to share," where you can physically exchange data with other devices using NFC or built-in antennas. You might not be tapping your laptop with smartphones for a while, but, again, it's a sign that Microsoft is thinking about mobile users.
