System Explorer is a tool for accessing a variety of system internals.
It can also be used as a Task Manager replacement with detailed
information about processes, startup entries, explorer/IE add-ons,
uninstallers, services, drivers, connections, opened files etc. It has a
registry/file snapshot feature so that changes to the system can be
computed and displayed in tree view or text list format. It also has a
processes security tool that checks your processes against an online
database.
