SYMPTOMS

You may experience one or more of the following symptoms intermittently when you use a third-party program that loads performance-monitoring extension dynamic link library (DLL) files on your Windows 2000-based or Windows XP-based computer:
  • Memory leaks
  • Slow performance or a program stops responding
  • Persistent event logging
  • Program unresponsiveness or crashes

CAUSE

This problem may occur because the Performance Monitor component (Pdh.dll) generates "Global" calls to the RegQueryValueExW function that causes all performance counters to be loaded, even though only specific objects may be requested by the running program. This problem may cause one or more of the symptoms if multiple extension DLL files that are incompatible or problematic are loaded at the same time.
