In "Taskbar and Start Menu" in the "Taskbar" tab, go to Customize and see what you can screw around with. Seems pretty useful in there. If that doesn't work:
Try going into Regional and Language Options. Then, go to the Languages tab and goto Details. From there, go to Advanced and try turning off Advanced Text Services. That might do it.
