First of all, I'd like to say that this is a biased opinion because I like Unix-like system.

I believe the reason companies use MS products is that it is easy to maintain and has a steep learning curve. In other words, MS products are easy to run. All you need to do is just clicking buttons.

Then, what the hell is wrong with MS Server Core Edition? It has a simple command line interface on which MS's own command line utilities operate. Those utilities are not easy to use. Even help commands don't show useful information. Not only that, but the style of commands also has nothing to do with any other styles other systems have been using. It's a waste of time.
