Part of our reality is that we have to maintain older guest operating systems on our hypervisors.
One of the many issues that come along with that is maintenance of Hyper-V’s Integration Services.
Failure of a provider caused the entire WMI service to fail; the next request to WMI restarted the service.
Beginning with Windows XP, WMI resides in a shared service host with several other services.
Beginning with Windows 7 and Windows Server 2008 R2, the Integration Services are built-in. As a great many of those previously mentioned tech writers are anxious to point out, Microsoft is planning to shift this behavior so that the Integration Services are delivered via Windows Update.
