Not Windowblinds! I am guessing what happend here :
Taskbar is hidden; a free start menu is placer in the top left corner insted.
Few gadgets are placed on the start menu to hide the programs list. Physically it is not possible.
two circle docks placed on two top corner with osx icons.
The bar at the bottom is rainmeter.
Its a manipulated scene to obtain screenshot, man! wouldn't be easy to work with
