The reason we decided to teach Windows was that most computers in the real world run on Windows. Strictly speaking, we shouldn't install pirated versions of Windows on those machines - which means one of two things can be done... Either we send an email to Microsoft explaining to them about this venture (Like we had done for Baraha previously) and they will either give us some free licenses or say that they will give it at discounted prices (Student versions). If it is the former, then nothing beats it. If it is the latter, we can always
tell them that we will opt for Linux instead. Or we go for the other option of installing pirated copies of Windows - which is not correct, but is rampant and everyone does it anyway (not that that justifies this :-) ) and nobody will ever know - I mean, most people run pirated versions on their personal systems anyway...
If you want to really stay above the law, then installing Ubuntu is a great idea. Installing Kubuntu may be a better idea because the interface is a lot similar to Windows with start buttons, taskbars, etc.
There is one other alternative in case people want bleeding edge technology delivered - Windows 8 is available for 1 year (or lesser now) as some kind of demo version. I myself haven't tried it out though. I am sure most people will find this option silly
In my opinion, Kubuntu (Ubuntu + KDE Environment) is the easiest and safest choice. Of course, it is up for people to decide
