SYMPTOMS
If an event consumer causes the registration of more than 64 concurrent notifications, all previous notifications are invalidated and will not receive their desired events.
STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
Windows Management Instrumentation (WMI) clients can receive notification of changes in the registry by using the Registry Event Provider. Clients can register to receive an event notification when:
- A value for a specific key changes.
- A specific key itself changes.
- One of the keys of the hierarchy of a certain key changes.
In order for a client to receive these event notifications, it must register itself as a consumer to the desired event. This is accomplished by executing a notification query which designates the desired key to be monitored. The query has the following form:
Select * from RegistryTreeChangeEvent where Hive="HKEY_LOCAL_MACHINE" and RootPath="SOFTWARE"
REFERENCES
For additional information, see "Registry Provider" and "Event Notification" in the WMI SDK documentation or MSDN Library.
