All features in custom utilities are available after installation of Windows 2000 or Windows XP

For all manufacturer-provided utilities preinstalled on the system, one of the following conditions must be met:

• 
  If no user functionality is lost after installing Windows 2000 or Windows XP, the utility can be removed or turned off. This case applies when built-in Windows 2000 or Windows XP features such as ACPI-based power management replace functionality that the manufacturer provided under Windows NT 4.0 through custom utilities.
  

• 
  If user functionality is lost, the manufacturer must provide customer support as described earlier in the item “Preinstalled applications and utilities are ‘Windows XP/Windows 2000 ready.’”
