How to activate:
Create one virtual desktop solely for watching video files and listening music, another one - for chatting or reading books, put your email client and browser windows on another and your text editor and debugger on a fourth one etc. Each virtual desktop - for a separate task. In such a way switching between desktops means switching between tasks.
Actual Virtual Desktops makes it possible to see applications' windows needed for accomplishing the required task. Need to solve another task - simply switch to another virtual desktop with the already prepared windows for it.
Never minimize any of the applications, never close any of them. When you switch virtual desktops, all running Windows® programs just disappear from the screen and from the taskbar, but they are right there waiting when you switch back to a separate screen.
