- the operating system: Microsoft Windows 2000
SUMMARY
The format of some performance counter data on Windows 2000 is different from the format of the performance counter data on Microsoft Windows NT 4.0. Also, the performance library (PerfLib) on Windows 2000 performs more checks than does Windows NT 4.0 for the performance data that is returned by a performance extension dynamic-link library (DLL). This article provides links to Microsoft Knowledge Base articles that document the changes that you may encounter when you move from Windows NT 4.0 to Windows 2000.
