Perhaps you meant to write: I have upgraded to Windows XP from a previous version of
Windows using a Windows XP Upgrade CD which I purchased, and now want to remove that
upgrade and go back to the original version of Windows 98 or Windows ME which I was using
prior to upgrading to Windows XP. If that is the case: If during the Windows XP Upgrade
install the Windows XP uninstall files were saved to your hard drive:
NOTE: If you upgraded from Windows XP Home Edition, Microsoft Windows
2000, or Microsoft Windows NT 4.0, you cannot uninstall Windows XP.
How to Uninstall Windows XP
1.. Restart your computer in Safe mode. To enter Safe Mode, press the F8 key while
when you power on your computer, but PRIOR to the Windows XP logo, and when the menu
screen comes up press the corresponding keyboard key number for SAFE MODE.
2.. Log on using the Administrator account.
3.. Click Start, click Control Panel, and then double-click Add or Remove
Programs.
4.. In the list of installed programs, double-click Uninstall Windows XP.
NOTE: If Uninstall Windows XP is not in the list of installed programs,
you must manually reinstall Windows 98 or Windows Me. If this is the case,
make sure to back up all of your critical data before you reinstall Windows
98 or Windows Me.
5.. When you receive the "Are you sure you want to uninstall Windows XP
and restore your previous operating system?" message, click Yes to start the
Windows XP uninstallation process.

will shutdown, restart, and then boot to the previously-installed operating
system.
