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.

Very much appreciated. Will go look at it.

This could be an old computer/Windows, or something. In the upper right hand of add/remove programs, there's only the ordinary minimize, expand, and close buttons and below that a Sort by pull down menu with options of : name, size, frequency of use, and date last used.
