Abstract: This paper mainly proposes an improved design of process monitoring system and describes methods of their realization, by analyzing the existing process monitoring software in Windows, then focusing on the shortcomings such as information of process is not enough in-depth or comprehensive, information classification is not clear. The system in the design is based on Microsoft Visual Studio 2005 platform, using MFC development. The system calls the Windows operating system ToolHelp32 library and PSAPI library for more detailed process information, and then classifies them to the "basic data", "time resources", "space resources" and "load module", finally uses the data tables, graphs, histograms and other means to demonstrate the results of monitoring. The design not only improves the user experience, but also provides the basis for the effective management of computer.

Key words: Windows, process monitoring, MFC, ToolHelp32, PSAPI, information classification, information display
