Windows 7 new features

The Windows 7 operating system shares many features and functions with Windows Vista. It also improves on Vista. Here is a list of features and functions that are unique to Windows 7:

• Action Center – allows users to see what alerts Windows 7 shows; a handy way to control those annoying UAC messages while not having to disable it.
   
• Aero Shake – click and shake one open window and all others on the desktop will minimize.
   
• Aero Snap – drag a window to any edge of the display and it will automatically re-size.
   
• Aero Peek - point to the right edge of the taskbar to watch open windows turn transparent, revealing all your hidden icons and gadgets
   
• Aero Templates, Themes – new backgrounds and themes unique and created for Windows 7 (including free additional themes downloadable from Microsoft).
   
• Device Stage - helps users interact with any compatible device connected to a Windows 7 computer; view device status and run common tasks from a single window. The key words here are "compatible devices."
   
• Domain Join – helps business users quickly connect to different office networks.
   
• Gadgets (Improved) – the Sidebar has been eliminated; Gadgets can be placed anywhere; New Gadgets have more functionality.
   
• Home Group – enables users to quickly and easily create home networks between computers using Windows 7.

• Libraries - make it easier to find, work with, and organize documents, music, pictures, and videos scattered across your PC or network.
