12 The *Ctx* minifilter demonstrates how to attach and remove contexts from instances, files, steams, and stream handles. *Ctx* attaches a context whenever one of these objects is created. While attaching a context to a file, the sample also creates a stream and stream handle context. All contexts are ultimately deleted by the filter manager using the callback function that the *Ctx* minifilter provides.
