The first thing I did when customising XP was to go back to the classic interface. I really hated the blue/green default task bar.

However, I have seen some desktops with really nice custom themes using transparencies and such.

All the websites I have come across on the net require the downloading of some third party software to allow the installation of their themes. Doesn't Windows XP have its own native custom theme support?

If not, what is the best third party software? I have tried Windows Blinds (which I believe XP uses anyway to some degree) and the little black browser back buttons were screwed up so I uninstalled it.

Thus, I'd prefer to use bug free software!

Thank you for your help.
