What Is Aero?

AERO stands for Authentic, Energetic, Reflective, and Open. It is to give a crisp new look to Windows Vista. The AERO only is available on Home Premium, Business, Ultimate, and Enterprise editions of Vista. The only benefit of AERO is the glass like look.
If you want to turn on and off AERO or change the setting:

• Right-click a blank area on the Vista Desktop
• Click on Personalize.
• Click on the link: Windows Color and Appearance
• Examine the Color Scheme
• 'Windows Aero' is the best choice.
