1.5 Upgrading vs. Installing a New Copy
After you start the Windows XP Setup Wizard, one of the first decisions you have to make is whether to upgrade your current operating system or to perform an entirely new installation. During the setup process, you must choose between upgrading or installing a new copy of Windows (a "clean install").
During an upgrade, the Windows XP Setup Wizard replaces existing Windows files but preserves your existing settings and applications. Some applications might not be compatible with Windows XP Professional and therefore might not function properly after an upgrade. You can upgrade to Windows XP Professional from the following operating systems:
* Windows 98 (all versions)
* Windows Millennium Edition
* Windows NT 4.0 Workstation (Service Pack 6 and later)
* Windows 2000 Professional (including service packs)
* Windows XP Home Edition
