When you uninstall Office 2000, it tends to leave tags ends – files as well as
registry entries. Microsoft has released a freeware utility, Office 2000 File
and Registry Eraser. This utility was not designed to uninstall Office 2000,
only to cleanup after the incomplete job done by Office 2000’s uninstall
program.
