Microsoft plans to discontinue support for Windows XP in April after 12 years on the market.
The problem: XP remains Microsoft's second most-used Windows operating system, according to NetMarketShare. XP is still miles ahead of Windows 8 - a lot of users resisted upgrading to Vista and more modern versions of the system because XP kinda got it right - it did everything that most desktop users need an operating system to do, and it was not complicated to use.
Windows 7 is the most popular system, as this chart of market share in the Windows environment from Statista shows.
