Testing Windows 10 Technical Preview
The new Start Menu. I don't regularly use the Live Tiles, but I like how they look.
The same menu but turned around to show the whole app list.
This is the famous preview of windows and multiple desktops. Cough cough, it has existed for centuries on Linux, cough cough.
This is a search box integrated in the task bar. When using it, it opens an app that searches the query using Bing.
This is how it looks on Windows 10 a Snap between 2 classic applications and 2 Modern UI ones.
