Windows 3.1 is very much different to the current windows versions. Not only to windows XP or vista, there are huge differences even between Windows 95 and windows 3.1.
Unlike other versions of windows, it runs on top of MS-DOS. You need to type `win` in command prompt to execute windows. Or you can add that command to autoexec.bat file to auto execute windows when computer starts.
I still have windows 3.1 installed in a virtual machine (just for fun :-) ). I think most of you haven’t seen this OS, so I decided to add some screen shots. You can see there is no close button (X) in windows (even though maximize and minimize buttons are there).
If you like to see how it looks like, you can download it and install it on a virtual machine.
