I always had a dual feeling about this. In one way, yes, at one point I also found myself tweaking KDE until it was even closer to Windows than it is by default. That works ok for me, and I am still unsure whether it is because I'm used to it or because it is just good or a combination. At the same time though I always found it amusing and interesting to try completely different WMs. But in the end I noticed I'm always going back to some standards in the end. And spent (wasted?) some time configuring/being annoyed/... because the WM got in the way or was lacking features rather than being helpful. So, like another commenter says: wouldn't mind a complete Windows UI clone (especially window/multiple monitor/keyboard behavior) on Linux.
