Windows Vista Requirements

The Windows Vista requirements are outlined in the Windows Vista Capable PC specifications. New computers that meet the requirements are eligible to carry the Windows Vista Capable designation. In order for a computer to meet the Windows Vista requirements, it must have:

• a 800 MHz or faster processor
• 512 MB of RAM
• A DirectX 9 capable graphics processor

Although Vista Capable PCs can run Vista, they don't meet the requirements for Windows Aero, one of the Vista features. Windows Aero is a new interface and visual style that includes live taskbar thumbnails, transparent window frames, and Flip3D. In order for a computer to run Windows Aero, it must meet the Vista Premium Ready requirements:

• 1 GHz 32-bit (x86) or 64-bit (x64) processor
• 1 GB of RAM
• Support for DirectX 9 graphics with a WDDM driver, 128 MB of graphics memory (minimum)2, Pixel Shader 2.0 and 32 bits per pixel
• 40 GB of hard drive capacity with 15 GB free space
• DVD-ROM Drive
• Audio output capability
• Internet access capability

Not all the Vista Premium Ready requirements relate exclusively to the needs of Windows Aero. The faster processer, greater RAM, larger hard drive, higher-end graphics procesor, and audio output and Internet access capabilities simply ensure the computer will have the hardware needed for you to enjoy a premium computing experience.

Although Premium Ready PCs will deliver faster computing and Windows Aero, you shouldn't be reluctant to upgrade to Vista simply because you only have a Capable PC. Capable PCs can run Vista without a hitch; I've been using Vista on a Capable PC for months.
