RuntimeClassesView is a tool that displays the list of Windows Runtime (WinRT) classes installed on your system. For every Runtime class, the following information is displayed: Class Name, Filename, Threading, Trust Level, Server, Activation Type, Registry Key, Bitness, Key Modified Time, CLSID, and file version information. When selecting a Windows Runtime class in the upper pane, this tool tries to get the list of interfaces implemented by the selected class and the list is displayed in the lower pane.
