__InstanceDeletionEvent class
The __InstanceDeletionEvent system class reports an instance deletion event, which is a type of intrinsic event generated when an instance is deleted from the namespace.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
Syntax
class __InstanceDeletionEvent : __InstanceOperationEvent
{
uint8 SECURITY_DESCRIPTOR[];
object TargetInstance;
uint64 TIME_CREATED;
};

Properties
The __InstanceDeletionEvent class has these properties.
-
SECURITY_DESCRIPTOR
-
-
Data type: uint8 array
-
Access type: Read-only
Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event.
-
-
TargetInstance
-
-
Data type: object
-
Access type: Read-only
Copy of the instance that was deleted. This property is inherited from __InstanceOperationEvent.
-
-
TIME_CREATED
-
-
Data type: uint64
-
Access type: Read-only
Unique value that indicates the time at which the event was generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Time (UTC) format. This property is inherited from __Event.
For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks
The __InstanceDeletionEvent class is derived from __InstanceOperationEvent.
Deletion of a resource: __InstanceDeletionEvent
If you want to ensure that a particular antivirus scanner program continues to run on a computer, you can write a script that monitors the processes on the computer to determine whether any of them stop.
Notification queries that request notification of the deletion of a resource and use intrinsic events all use syntax similar to the following:
SELECT * FROM __InstanceDeletionEvent WHERE TargetInstance ISA 'Win32_Process' and TargetInstance.Name = 'notepad.exe'
