932616 Installation choices for consumer versions of Windows Vista (32-bit only)


INTRODUCTION

This article discusses the installation choices for 64-bit consumer versions of Windows Vista. This article does not include information about Windows Vista Starter, Windows Vista Enterprise, or versions of Windows Vista that you install by using Microsoft Volume Licensing.

The method that you use to install a 64-bit bit version of Windows Vista depends on the answers to the following questions:

  • Is your current operating system 32-bit or 64-bit? See the definition of a 64-bit operating system in the "General information about how to install the 64-bit version of Windows Vista" section for more information.
  • Do you have an upgrade license for Windows Vista or a full product license? This is described on the Retail box cover and on an online sales receipt.
  • Does the version of Windows Vista that you purchased support an upgrade for the version of the operating system that is currently installed?
  • Do you want to preserve your personal files, settings and programs? Or do you prefer to perform a clean installation of Windows Vista?

General information about how to install the 64-bit version of Windows Vista

Definitions

  • An upgrade to Windows Vista An upgrade to Windows Vista preserves the personal files, the settings, and the programs that are currently installed. You can upgrade only from one 64-bit version of Windows Vista to certain other versions of Windows Vista. See the individual upgrade paths later in this article to find out whether this option is available for your current operating system.
  • A custom Installation or a "clean installation" of Windows Vista A custom installation of Windows Vista does not preserve the currently installed personal files, settings and programs. A custom installation is also known as a "clean installation." Windows Vista is installed without third-party programs. You can perform a custom installation of Windows Vista by using either an upgrade license or a full product license. However, if you own an upgrade license, you must select Custom at the installation choice menu to perform this action. Note your particular upgrade path for complete details on how to perform this installation type
  • An upgrade version of Windows Vista An upgrade version of Windows Vista is a license that lets you install Windows Vista only if you already own a license for a compliant version of Windows. Such compliant versions include versions of Windows Vista, Microsoft Windows XP, or Microsoft Windows 2000. You can perform either an upgrade installation or a custom installation of Windows Vista by using an upgrade license.
  • A 64-bit operating system Windows XP Professional x64 was the first widely-available consumer 64-bit Windows operating system. Windows Vista comes in a 64-bit version for every consumer brand. These brands include the following versions:
    • Windows Vista Home Basic
    • Windows Vista Home Premium
    • Windows Vista Ultimate
    • Windows Vista Business

    The 64-bit versions take advantage of the new 64-bit CPUs that are produced and sold in most new computers.

    Most Windows XP users have a 32-bit operating system for the following versions:

    • Windows XP Home
    • Windows XP Professional
    • Windows Media Center Edition
    Although you can install a 32-bit operating system on a computer that has a 64-bit CPU, you cannot install a 64-bit operating system on a computer that has a 32-bit CPU.
  • Upgrading a 32-bit operating system to a 64-bit operating system If you purchase a 64-bit upgrade version of Windows Vista with the intention of installing on a computer that is running a 32-bit operating system, you must install Windows Vista by starting the computer from the 64-bit Vista installation DVD.

    Important Do not remove the previous operating system before you start the Windows Vista installation. This is because Windows Vista Setup has to verify that your current operating system license supports the installation of a 64-bit upgrade version.
  • "N" versions of Windows Vista The "N" versions of Windows XP and of Windows Vista do not include Windows Media Center. You cannot perform an upgrade installation of an "N" version of Windows. Instead, you must perform a custom installation.
