For AAC files ripped fro CD using iTunes, show the album artwork in the WMP library.

Currently, there isn't any WMP tag support plug-in that I know of that supports embedded album art. WMP Tag Support Extender's development has been stopped, so album art support definitely won't be added to that.
However, the next major version of the WMP Tag Plus plug-in ( http://bmproductions.fixnum.org/wmptagplus ) will support embedded album art.
