Security is the main problem that Windows operating systems are facing since their
introduction. Lack of vision from its developers regarding security is probably the main
reason behind this issue. The first windows were designed to be simple and productive
but not very secure. Although new operating systems version were introduced almost 5-
10 years the same issues with security persisted. In my opinion, because of market
pressure and product development circles it was almost impossible for Microsoft to
totally change their operating system approach; instead they continued to build on top of
each previous model. Unfortunately, their operating systems are still vulnerable affecting
significantly ICT applications worldwide.
