I prefer Windows classic to windpws Xp's blue and silver i like the green but got tired of them now i use the Vista Transformation pack #4 it looks nice!
No good themes at all lately on DeviantArt and some other themes + Vista wannabe's are getting old. This is the only clean theme I know of out right now:
sometimes i prefer an older look and sometimes i prefer a modern sleek look and sometimes i prefer a kind of bulky theme. idk it really just depends on what mood im in.
