I also use the faves menu towards the top left of the screen in IE9.
In IE10, I think the only option is, to the top Right of the screen, there are 3 symbols: a house, a star & a cog. The Star is the Faves menu now.
Having said that, I thought I was running IE10,,,, but still have my faves in the same (old) place.
Am I really using 10 now ?
