Microsoft is considering bringing virtual desktops to Windows Threshold. The feature, which is already on other platforms like Ubuntu and OS X is currently being tested and is said to have similar functionality to that of Ubuntu. You can activate the desktops with a button on the taskbar (subject to change) and there are keyboard shortcuts that let you jump between active desktops.
Of course, this should have been done eons ago, but the fact they're considering it now is great news. Let's hope it's true.
