of Intelligent Manageability that allows you to view information

about the hardware and software configuration of your computer

while running Microsoft Windows (Microsoft Windows 98,

Microsoft Windows Me, Microsoft Windows 2000, Microsoft

Windows NT 4.0, and Microsoft Windows XP). It also allows you to

perform hardware and software tests on the subsystems of your

computer.

not log in as the administrator, you will be unable to test some

subsystems. The inability to test a subsystem will be indicated by an

error message under the subsystem name in the TEST window or by
