Needless to say, users on these unsupported operating systems are a particularly tempting (and easy) target for attackers, which is why we urge you to use an actively supported and updated operating system right away.

Of course, having so many users on outdated and unsupported operating systems poses a major security concern, as these operating systems have numerous, well-known security vulnerabilities but are no longer receiving any kind of support or system patches to fix those issues. Vista was sandwiched between these two operating systems, and often found itself overshadowed by XP’s popularity and longevity in the market: Vista was released more than five years after XP, but Vista’s commercial support was pulled by Microsoft two years before XP’s extended support was up. Even at its peak, Vista only held about 30% market share, nowhere near the ubiquity of its predecessor Windows XP or its successor Windows 7.
