Litestep was fine. Did not see it reduce windows "bloat" or whatever. Last I checked, depending on the module, Litestep can take MORE memory than IE. Got rid of it because not all apps work with it. Also, messes with Environment Variables, they don't take right sometimes. Turn off Lightstep, restart, change variable, restart, maybe enjoy... maybe. Got old quick. Messes with the language/multiple keyboards bar.
I keep my OS interface the way it is minus some user settings.
