The world would be stuffy, or they would just have holes as windiws, or they might call windows some thing else??!!..
Glass windows are called windows because with the help of glass windows you can see the outside world even without open the window unlike the normal window.
Windows on a plane (except the cockpit and entry/exit doors) do not serve a purpose only to allow passengers a view to the outside world. In fact, planes would be lighter without windows saving fuel and money. This would make for a boring plane ride, however!
Windows is the operating system on a Microsoft computer or an Apple computer running windows drivers. Without windows your computer would not work.
it would die
The world would suck without skate boarding because without it what would be fun?
A world without Buddhism.
Perfect World is only available for the Windows operating system so the Mac would need to have Windows installed to be able to run Perfect World.
the world will be like a body without soul
Without money the world would have been dominated by barter trade
The world would be round xD
One word to describe 'What this world would be without rules' would be chaotic.
There would be many foggy multipane windows and light bulbs would implode much more often.
