SYMPTOMS

On a Windows Vista-based computer, when you run an application that uses the Refresh method of the IWbemRefresher interface, a memory leak may occur.

After the application runs for several days, the computer may become unresponsive. In this case, you have to restart the computer.

Additionally, if you use system performance monitor tool (Perfmon.exe) to monitor the Private Bytes counter of the application, you may notice that the private bytes increase quickly.
