Windows Vista (2007)
Windows 7 (2009)

Windows
comes pre-loaded on most new PCs and nowdays it is the most popular operating system in the world.
Mac OS
Mac OS is a line of operating systems created by Apple. It comes preloaded on all new Macintosh computers, or Macs. All of the recent versions are known as OS X (pronounced O-S Ten), and the specific versions include El Capitan (released in 2015),Yosemite (2014), Mavericks (2013),
Mountain Lion (2012), and Lion (2011).
According to Statistics, Mac OS X users account for less than 10% of global operating systems—much lower than the percentage of Windows users (more than 80%). One reason for this is that Apple computers tend to be more expensive. However, many people do prefer the look and feel of Mac OS X over Windows
