Ever seen an Operating System in a web browser, your answer might be no ! Then why not have a look at this one – this is one of the first operating system you would have ever seen before – Online virtual operating system – which has been rolled out by windows4all.com, and developed by using Microsoft Silverlight.

When you browse to windows4all.com, it will request us to install Sliverlight on to desktop, if you have already installed the same on to your desktop, then you will be directly redirected to the Operating System i.e. Windows Vista , if you are installing Silverlight for the first time, it will request you to restart the Browser. After installing, just browse to windows4all.com.

You can view Virtual Operating System right in your respective browser, it has a start button (like Windows Vista and older versions), File Explorer (Like Windows Explorer), a Media Player, a Notepad, RSS reader, Paint application, Games like Chess, Solitaire, Spider, Tic-tac-toe, and many more… The most interesting part is that you can also play .wmv and .wma media files in Media Player directly from Local Drive, i.e. from your Hard Drive.

This virtual operating system also supports installation of programs, but the respective program should be developed in Silverlight and be available on Internet or local file system. This online virtual operating system is in alpha stage now ! And will get more features added in future
