        Windows
        2000 Bugs & Fixes 
        No
        Uninstall Available After Upgrading to Windows 2000 
        The
        information in this article applies to: 
        
          - Microsoft
            Windows 2000 Professional
        
  
        SUMMARY
        When you upgrade from Microsoft Windows 95, Microsoft
        Windows 98, or Microsoft Windows NT to Windows 2000, the Setup wizard
        displays a warning message informing you that your current operating
        system will be replaced if you continue. Windows 2000 does not contain
        an uninstall feature to let you return to your previous Windows
        operating system. 
        MORE
        INFORMATION
        You should make a complete system backup before you
        upgrade to Windows 2000. Restoring this backup is the only way to return
        to your previous operating system as it was before you performed the
        upgrade.
