Windows Aero features in Windows 7 has been greatly enhanced and improved with new features such as Aero Peek. Without Windows Aero Glass Transparency effect, the many premium user interface (UI) goodies and extravaganza visual experience such as windows with translucent glass design and new windows colors in Windows 7 won’t be enjoyed by the system users.

In most circumstance, if the PC’s display card satisfy the minimum requirement to run Windows Aero, which appears to be not much different to what’s required in Windows Vista – 1 GHz 32-bit (x86) or 64-bit (x64) processor, 1 GB (gigabyte) of RAM memory and a DirectX 9 compatible GPU with a minimum of 128 MB of Video RAM, installed with Windows Display Driver Model (WDDM) driver – Windows 7 will automatically enable and turn on Aero upon installation.

However, in some scenarios, Windows Aero may not be turned on, or is having problem to enable. The scenarios include no supported video driver been found during installation, and after updating the VGA graphic display card driver, Windows 7 does not automatically enable Aero Glass effect. Or, Windows 7 is installed on a computer which barely meets the minimum requirement, and Windows 7 has a hard time deciding that it’s indeed able to run Windows 7 Aero without problem.

The score (both base score and subscore for graphics component) should be equal or higher than 3.0 for Aero to work. To view your Windows Experience Index, go to Control Panel -> System and Security -> System, then click on “Windows Experience Index”.
