Hurrah, my Windows XP desktop now looks much more like Linux, thanks to a utility called Style XP and the Nautilus RC4 theme available from themexp.org.
It all came out of frustration that Windows XP only comes with 3 color schemes, 2 of which were ugly, and the third one (Silver) got boring after using it for a year. And somehow the system won’t allow you to define your own color scheme, unless you switch back to the ancient Win95/98 look.
Anyway, I’m a lot happier now. The window title bars aren’t as ridiculously huge as they normally are, either.
