Get a list of mutex?

A program creates a mutex as part of its start-up. I don't know the format of this mutex so I wondered if there is a way to get a list of all non-abandoned mutex, open the program, get a new list and see if I can find the mutex by removing all duplicate entries. Is there a way to get this list?

handle -a | findstrで直接mutantの名前を指定しちゃっていいみたいだ。WinObjでももちろん確認できた
