What is a Windows Vista Capable PC?
A new PC that carries the Windows Vista Capable PC logo can run Windows Vista. All editions of Windows Vista will deliver core experiences such as innovations in organizing and finding information, security, and reliability. All Windows Vista Capable PCs will run these core experiences at a minimum. Some features available in the premium editions of Windows Vista—like the new Windows Aero user experience—may require advanced or additional hardware.
A Windows Vista Capable PC includes at least:
* A modern processor (at least 800MHz1).
* 512 MB of system memory.
* A graphics processor that is DirectX 9 capable.
Windows Vista Premium Ready PCs
To get an even better Windows Vista experience, including the Windows Aero user experience, ask for a Windows Vista Capable PC that is designated Premium Ready, or choose a PC that meets or exceeds the Premium Ready requirements described below. Features available in specific premium editions of Windows Vista, such as the ability to watch and record live TV, may require additional hardware.
