I am using Sound Forge to convert a 64kbps windows media file to a wav file. Is it possible to use the Equalizer Process to restore some of the complexity to the music that may have been lost in the compressed format? For example, is the strength of the high frequencies reduced in the compressed format? Would a treble boost help restore this loss?

"Is it possible to use the Equalizer Process to restore some of the complexity to the music that may have been lost in the compressed format?"
--With a file rendered at 64 kbs, probably not much.

"For example, is the strength of the high frequencies reduced in the compressed format?"
--Yes, the very high frequencies are cut completely in both wma and mp3 formats.

"Would a treble boost help restore this loss?"
-- A gradual high-shelf boost above 10 khz might help the perceptual effect a bit.

Somewhere I saw a utility or plug that claimed to restore high frequency loss in compressed formats, however it would have to work by extrapolation, don't know how good the "restoration" would be....

Although you may be able to make the file "sound" a bit better, there's nothing to actually restore. You can't "un-compress" the file or enhance a fequency that no longer exists in it.
As mentioned above, you certainly should be able to make it more pleasing but keep your expectations in context.
