MMC (Microsoft Management Console) Snap-ins are Windows components typically used for various Windows management tools - Event Viewer, Device Manager, Task Scheduler and more - although third-party developers also add them occasionally.

MMCSnapInsView is a tiny portable tool which lists the details of all snap-ins installed on your PC.

The information is presented in the standard NirSoft table, and includes snap-in name, description, CLSID, dll file, product name, company name, file version, and more.

The data can be saved as a report.

Perhaps most usefully, you're able to select multiple snap-ins and open them all in a single console.
