Why did Microsoft make Windows 7 in 6 different versions? -

It does that to be able to add the optional features (and so additional cost) to people who only need them. So home user may not need administrative kit that a Server PC may require.

Different strokes for different folks. Different price points, different features, different uses, different system requirements, etc.

prolly cause they want money they don t really need 7 version they if they really needed more then one version they just should have done what they did with XP and release a home and professional
