Despite being abandoned by Microsoft over three years ago, Windows XP is still the world’s third-most popular operating system. According to the latest statistics, it is still installed on 7.04 percent of computers around the world, eclipsed only by Windows 7 and Windows 10. Read More Windows XP is still more popular than Windows Vista, and 8, and all Apple, UNIX and Linux operating systems. I wonder would XP ever rise to the second most popular operating system as people upgrade to Windows 10, ditch Windows 10 because of privacy, reliability and security concerns, and switch to Chrome OS, Android based OS, Linux, and less popular operating systems like UNIX/FreeBSD. A lot of older software, games, hardware/computers, and accessories like printers may not work on Windows 7, and 10, so a lot of people still need to use XP, or spend hundreds to thousands of dollars on new software, similar games which work on 7 and 10, accessories, and hardware which work on Windows 7 and 10. Plus, many people want to continue playing older games which may not work on Windows 7, 8, and 10 because the maker of the game is retired, or the company is not supporting the game anymore.
