I don't really care too much about replacing original Windows the desktop, taskbar and system tray. I really dislike the new Windows 7/Vista Windows Explorer:
What I'm trying to figure out is whether BB4Win or its plugins have a replacement for it. The bb4win website pretty much doesn't make sense to me. I'm using Win7 64 bit.
Also, off-topic ... I was looking at a related question on this site here: Good Windows shell replacement
