WMI service crashes randomly in Windows Server 2012 R2 or Windows Server 2012

This article describes an issue in which Windows Management Instrumentation (WMI) service crashes in Windows 8.1, Windows RT 8.1, Windows Server 2012 R2, or Windows Server 2012. An update is available to fix this issue. Before you install this update, see the Prerequisites section.

Symptoms


When this issue occurs, you may experience the following problems:
  • Every functionality that uses the WMI interface would fail. For example, Virtual Machine Manager (VMM) uses the WMI interface to show the status of virtual machines (VMs) on a Hyper-V host. If the WMI service on that Hyper-V host crashes, VMM can't show the status of the VMs on that host.
  • All services that share the same service host process with the WMI service would also become unavailable. Therefore, you may experience other problems that are not related to WMI service itself.
