System Requirements

  • This tool works on Windows 10 and Windows 11. Both 32-bit and 64-bit systems are supported.
  • This tool is just a small standalone .exe file that you can run on any system without installing anything.

Start Using RuntimeClassesView

RuntimeClassesView doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - RuntimeClassesView.exe
After running RuntimeClassesView, the main window displays the list of all runtime classes installed on your system. If you want to find a specific runtime class, you can press Ctrl+Q, and then in the quick filter window, type the string you want to find.
When you select a single runtime class in the upper pane of the main window, RuntimeClassesView tries to get the list of interfaces implemented by the selected class (By calling the IInspectable::GetIids method ) and the list is displayed in the lower pane.

You can also select one or more runtime classes (or select all of them by pressing Ctrl+A) and then export them to tab-delimited/comma-delimited/HTML/XML/JSON file by using the 'Save Selected Items' option.

Command-Line Options

/stext <Filename> Save the runtime classes list to a simple text file.
/stab <Filename> Save the runtime classes list to a tab-delimited text file.
/scomma <Filename> Save the runtime classes list to a comma-delimited text file (csv).

/sort <column> This command-line option can be used with other save options for sorting by the desired column. The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Class Name" and "Filename". You can specify the '~' prefix character (e.g: "~Key Modified Time") if you want to sort in descending order. You can put multiple /sort in the command-line if you want to sort by multiple columns.
