When a component wants to add a dynamic key to the Registry namespace, it calls the RegCreateDynamicKey VxD service.
Notes
1. Dynamic keys are like volatile keys in that they disappear when the hive they are in is unloaded
2. Providers have no knowledge of the sub-keys under their dynamic keys. They just provide data for their key/values
3. RegNotifyChangeKeyValue will return ERROR_NOT_SUPPORTED when called against a dynamic key
4. For dynamic keys, the lastWriteTime parameter in RegQueryInfoKey returns the time when the key was created
