Intel Pentium or Celeron CPU Identified Incorrectly

This article was previously published under Q216204
SYMPTOMS
When you run the Microsoft System Information tool or view the General tab in System properties, the Intel Pentium III or Celeron Central Processing Unit (CPU) in your computer may be listed as an Intel Pentium II CPU or an Intel Pentium Pro CPU. Also, the processor type may be displayed instead of the "friendly" processor name.
CAUSE
This behavior occurs because Microsoft Windows is aware of only those friendly processor names that existed when Windows was developed. For example, if a new name came out after Windows was released, that name would not be available in that version of Windows.
RESOLUTION
To work around this behavior, please consult the documentation that was included with your computer to determine which CPU you have, or use a third party utility specifically written that identifies processor type and speed.

An example of such a program is the Intel Processor Frequency ID utility. This utility should provide the correct information about your processor type and bus speed. To download this utility, for Windows 95, Windows 98, Windows Me, Windows NT, and Windows 2000, view the following Intel Web site: Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.
