Hardware requirements

Computers capable of running Windows Vista are classified as Vista Capable and Vista Premium Ready. A Vista Capable or equivalent PC is capable of running all editions of Windows Vista although some of the special features and high-end graphics options may require additional or more advanced hardware. A Vista Premium Ready PC can take advantage of Vista's high-end features.

Windows Vista's Basic and Classic interfaces work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA GeForce 6 series and later, the ATI Radeon 9500 and later, Intel's GMA 950 and later integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported. Although originally supported, the GeForce FX 5 series has been dropped from newer drivers from NVIDIA. The last driver from NVIDIA to support the GeForce FX series on Vista was 96.85. Microsoft offers a tool called the Windows Vista Upgrade Advisor to assist Windows XP and Vista users in determining what versions of Windows their machine is capable of running. Although the installation media included in retail packages is a 32-bit DVD, customers needing a CD-ROM or customers who wish for a 64-bit install media are able to acquire this media through the Windows Vista Alternate Media program. The Ultimate edition includes both 32-bit and 64-bit media. The digitally downloaded version of Ultimate includes only one version, either 32-bit or 64-bit, from Windows Marketplace.
