Windows XP Upgrade Installations Chapter 1, 'Windows Version History,' introduced you to the various versions of Windows, past and present, and briefly mentioned the features of Windows XP. ![]() Large numbers of individuals and companies still have older versions of Windows running on their computers. And even with Windows Vista on the horizon, compared to these older versions, Windows XP still offers a user-friendly experience and security functions that go far beyond its predecessors, including Windows 2000. In Chapter 2, 'Installing Windows,' we talked about baseline Windows XP installation concepts and features as well as how to perform clean and professional installations of the XP operating system. In this chapter I cover how to perform an upgrade Windows XP installation, in which Windows XP replaces a previous Windows OS without first removing all data from the system drive and starting from scratch. An upgrade installation is most useful in cases where you have customized user settings that you want to preserve. This option, however, does not always work flawlessly, especially if you are upgrading from an operating system other than Windows 2000 Professional or Windows XP Home Edition (to XP Pro) due to the differences in the Registry structure and the startup process. Stability issues aside, if you allow Windows XP to back up the existing operating system during the upgrade you can later uninstall Windows XP and effectively revert your computer back to the state it was in immediately preceding the Windows XP upgrade. The ability to uninstall is contingent on the disk volume being FAT32 and not NTFS, that you have not created or deleted any disk volumes on the system, and that you do not delete any backup files created during the upgrade installation process. Deciding Whether an Upgrade is Worthwhile Most individuals and companies acquire Windows XP installed on a new computer. However, a large established base of existing computers running older versions of Windows is present in nearly all organizations. Although nearly everyone would like to take advantage of the new capabilities of Windows XP, upgrades are not always feasible. First and foremost, there is the significant cost of new software and its licenses. In addition, you need to take into account the following: • Many older computers lack the hardware resources required to run Windows XP. • You cannot upgrade all operating systems directly to Windows XP. • Upgrading a large number of computers on a network involves a considerable investment in time and money. • Applications running on existing computers may not be compatible with Windows XP. Available Upgrade Paths Possible upgrade paths for computers running older Windows operating systems depend on the operating system currently installed as well as the version of Windows XP you plan to install. Table 3.1 outlines the available upgrade paths. ![]()
