Windows4all is a Microsoft Silverlight based online virtual operating system. It is a website that simulates an operating system inside a web browser. Windows4all.com replicates the desktop environment of a modern operating system. The user can launch applications right away without installation.
Are you assuming that above screen shot is showing my desktop. No, this is the Windows4all desktop view. At first glance, you will would not believe that it’s just virtual version of web based Windows.
Windows4all.com requires Silverlight 2 player to operate because it was developed on Microsoft Silverlight. Besides desktop, taskbar, start menu and sidebar, currently it includes such applications.

* File Explorer
* Internet Explorer
* Video Player
* Rich text editor
* RSS reader
* Notepad
* Paint
* Calculator
* Games like Chess, Solitaire, Spider, Tic-tac-toe
The system also supports installing program functionality. But this program should be developed in Silverlight and be available in Internet or local file system. This is the alpha version of Windows4all.com but it’s still wonderful.
Update: Thank you Akmal Wardak for your point. After you commented here, we have figured out that Windows4all is not a Microsoft product and we have mistakenly Introduced it like this. We apologize to our community.

Its clear that this thing is not developed by Microsoft. like can’t you just tell that from reading the name “windows4all”.
and then the last paragraph of the post is just copied from a read-me file, and says that it supports installing additional software. I couldn’t find out how.
worst of all is the title of this post.
i will rank this on top as one of those stories that says one thing in the title and is actually another thing. just to gain attention???
I was kind of alarmed that when I opened up the Internet Explorer icon then went to google.com to test, I was already logged in under my normal login for google. I think I’ll change my password and never go back to that site just to be safe ![]()






This could s*ck with people using slow internet..
