While working on my friends computer today I decided to mess with him, and was going to replace his Shell with KDE plasmas Shell...but that doesn't work so great by itself, so I set plasma to start with windows, which works extremely well, as you can see here, this is my machine with windows 7, running KDE SC 4.7. Not every day you see KDE widgets and Win 7 widgets working side by side. I tried to get kicker and windows start menu to both be open at the same time to grab a screenshot of that, but it just wasn't happening :).
The only downside to this, The KDE SC doesn't use kwin :(, but I find it rather neat none the less.
If any one is interested in running KDE on windows, I download the installer from here, and found the plasma-desktop.exe and started it up. They have directions on their site to replace explorer.exe with plasma, but I couldn't get it to work correctly, but it be interest to hear from any one who plays around with this and can completely replace explorer.exe shell with KDE :).
