KWin is the window manager for the KDE Plasma Desktop. It gives you complete control over your windows, making sure they're not in the way but aid you in your task. It paints the window decoration, the bar on top of every window with buttons like close, maximize and minimize. It also handles placing of windows and switching between them.

KWin supports compositing, which means using 3D effects for handling your windows. This can make window management smoother, easier, more efficient and more natural. It's hardware requirements are very modest and pretty much every reasonably modern system since 2002 supports it.
