Blizzard recently announced that they will end support for all of their titles on Windows XP and Windows Vista, operating platforms that are currently entering their 16th and 11th years, respectively.
With the release of three new Windows OS (Windows 7, Windows 8, and Windows 10) over the last decade, the company believes the majority of their player base has already upgraded to these newer versions of Microsoft's operating system. Blizzard is currently planning for a staggered schedule (of which, again, there is no definite initiation date) to phase out Windows XP and Windows Vista support.
Windows XP is considered to be one of the most successful operating systems in Microsoft family. Despite Microsoft ceasing support of the OS back in 2012, its popularity had helped the OS live on amongst adopters. Furthermore, Windows XP has been widely considered the most compatible OS for older Windows-based games than later operating systems like Windows 7 and Windows 10.
