A great example of Windows' evolutionary drawbacks
If you have ever tried working through an NSA guide on securing Microsoft IIS you will appreciate how many internal systems exists under the hood of Windows and their many deficiencies. For those that have been fortunate to not go through the experience Richard Stiennon uses some compelling visuals by Sana Security to explain why Windows is less secure than Linux because of its long evolutionary history.

Consequently whilst Windows works what goes on under the hood is not pretty and very difficult to secure.
