If a stream context is associated with a stream (ie. FltSetStreamContext has
been called). Will a FltDeleteContext act just like FltDeleteStreamContext
and remove the context from the stream AND mark it for deletion or just mark
it for deletion?
What is the difference aside from the fact that Delete takes one parameter
and DeleteStream takes three?
Can I use FltDeleteContext if I have not previously done a
FltGetStreamContext?

You use FltDeleteStreamContext if you don’t have the context in hand and
want to delete it (it does the lookup, then deletes it). If you ask for
the deleted context to be returned (the 3rd parameter), you must call
FltReleaseContext when you are finished with that context.
You use FltDeleteContext if you already have the context. This call
does not release the reference you added to the context when you called
FltGetStreamContext to retrieve it.
