Those are only for programs.

Is there a way to look at things recently added to a computer (small things, not entire programs, such as plugins, patches, updates, etc.)? Is there some sort of log?

As you can see, the question is asking for things such as plugins, patches, updates, etc.

Appreciated anyway.

There's a "show updates" checkbox in the upper right corner of Add/Remove programs. That will show you patches and updates.

Or, you can open a command prompt and run wmic qfe.

Neither of those will show you browser plug-ins though.
