This article describes an issue when you run the Windows Management Instrumentation (WMI) query in Windows Server 2012 R2 or Windows Server 2012. You can fix this issue by using the update or hotfix in this article. Before you install this update or hotfix, see the Prerequisites section.
Symptoms
Assume that you have an application that queries scheduled tasks periodically through WMI to Root\Microsoft\Windows\TaskScheduler\MSFT_ScheduledTask. Every time the WMI query runs, the WMI provider process memory usage increases. Eventually, the memory usage reaches the WMI provider process quota, and no more WMI queries can be done in this process.
Cause
This issue occurs because of a memory leak in the Wmiprvse.exe process when you run WMI queries to monitor scheduled tasks.
