Browse COM Classes
The Tools / Browse COM Classes command scans the system registry and shows all the COM classes registered in the system.
Select a class in the Registered Classes list to scan it for supported interfaces. Please note that scanning is not always possible and sometimes interface scanning may cause the corresponding program to start or to report an error.
Selecting a class or an interface and pressing the Copy button copies the selected GUID to the clipboard. The command copies the binary GUID as well as the textual representation in the curly brackets. Which one is pasted depends on which pane you are pasting to.
