Windows Multiple Desktops

I was looking for a virtual desktop solution on windows platform so that I can manage my works easier and don't get caught in a messy screen full of windows! Microsoft has provided a free tool on it as part of its PowerToys package (Virtual Desktop Manager) but I was expecting something more flexible which I finally ended up with VirtuaWin. With VirtuaWin you can easily move between four different desktops and transfer your open windows to any desktop you like.
