If you took all the remaining Windows XP and Vista users in the world—a surprisingly robust 10 percent—and placed them in a Venn diagram with those that play Blizzard games, the intersection would likely be very, very small.

And yet, despite Microsoft ending mainstream support for XP and Vista in 2009 and 2012 (Windows XP limped on with security updates until 2014), Blizzard has continued to support World of Warcraft, StarCraft 2, Diablo 3, Hearthstone, and even Heroes of the Storm under the decrepit operating systems.

Or, at least it did. Beginning “later this year,” Blizzard will sunset support for those games under XP and Vista. The change will be rolled out on a “staggered schedule,” with Blizzard promising to post individual notices for each game. The games will refuse to run on an unsupported operating system once support ends.
