GetOriginatorProcessName return null in WriteCallback Event

This is correct. GetOriginator* methods should be called only in response to file create and open requests. In those requests you should to obtain originator-related information (if you need it) and store it somewhere and place a reference of some kind to UserContext. Then in other callback handlers analyze information stored in (or referenced by) UserContext. The reason is that some operations can be initiated by system components (cache manager etc) for which GetOriginator* functions return no information. But these operations are performed on files opened by some process, so even if GetOriginator*() return no info, UserContext, which you have set up in create/open callback handler, will be valid.

Sincerely yours
