4657: A registry value was modified
On this page
This event documents creation, modification and deletion of registry VALUES. This event is logged between the open (4656) and close (4658) events for the registry KEY where the value resides. See Operation Type to find out if the value was created, modified or deleted. Of course this event will only be logged if the key's audit policy is enabled for Set Value permission for the appropriate user or a group in the user is a member.
