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
If your computer is currently running an unsupported
operating
system, you must install a new copy. The wizard installs
Windows XP
Professional in a new folder. After the installation is
complete, you
will have to reinstall applications and reset your
preferences.
