The Aero Desktop is really nothing more than a collection of window and desktop behaviors that make Windows 7 the prettiest version of the operating system to date. Features such as Aero Snap let you quickly organize open windows and transparency makes it easy to see what’s underneath other windows. With Windows XP think opaque, with Windows 7, think translucent.

Difference between Win.7 & Win. Vista

Performance and User Friendly

Windows 7 will reduce the time to install an app. Also, now Windows will be less annoying with very less UAC prompt. For developers also, Win7 will reduce the time taken for developing Windows app.

Security

Vista has never been known for having good security. UAC or User Account Control was introduced with Vista and later kept in Windows 7 but with additional controls and improved functionality. UAC is simply a security feature that helps to block viruses and malware. Although it isn’t bullet proof, it certainly limits what certain types of malware can do to your PC.
