Note Windows 2000 and Windows 2000 Professional can only be upgraded to Windows XP Professional. You cannot upgrade Windows 2000 to Windows XP Home.
Important Before you start the upgrade process, contact your computer manufacturer to obtain the latest BIOS upgrades for your computer and then install the upgrades. If you update the BIOS after you upgrade the computer, you may have to reinstall Windows XP to take advantage of features such as Advanced Configuration and Power Interface (ACPI) support in the BIOS. If you can do this, update the firmware in all the hardware devices before you start the upgrade.
You may want to disconnect from the Internet during the installation. This step is not necessary, but disconnecting from the Internet during the installation helps protect your computer. For added protection, you may also want to enable the Microsoft Internet Explorer firewall. For more information, see the "Enable or disable Internet Connection Firewall" topic in your Windows operating system Help. For more information about how to prepare Windows 98 or Windows Millennium Edition for an upgrade to Windows XP.
