Jump Lists provide users with quick access to a mini-Start menu containing lists of pictures, music, word documents or links that they use most frequently.
Taskbar Peek
This feature applies the Aero Peek technology to taskbar thumbnails.
Aero Snap
Maneuvering between windows is a pain, and comparing the content of two windows side by side requires awkward resizing that never quite works.
UAC
Four Options for notifications from always being notified to never being notified, including only getting warnings when software is installed.
Bit locker
BitLocker To Go Protection. BitLocker® has become a saving grace when it
comes to increased laptop security. Windows 7 has taken security even farther
with its BitLocker To GoTM feature, which allows you to encrypt removable USB
devices and external disks. To enable BitLocker or BitLocker To Go, right click the
drive in Windows Explorer and select “Turn on BitLocker…” This can also be
managed centrally via Group Policy, so IT administrators can require the USB
drive be encrypted before files can be written to it.
