i think u can add/remove any meter on desk as u wanted. forgot la..
i think u just enabled the font cleartype. it'll change the windows font to be blurry(cun meh!).  so, u just have to disable the cleartype font.. just use default font type.

haha.. dat's messed up dude.. seeing ur screenshot, i don't know if dat's the cleatype doings.  maybe it's something else. nway, just give it a try.u can download tweakUI to do that. google it k.
