If you love playing Blizzard games but have an aversion to upgrading your older operating systems on PC, then be prepared to force yourself to make a change if you still want to play World of Warcraft, Diablo 3, StarCraft 2, Hearthstone and Heroes of the Storm.
Blizzard has announced that it will be ending support for Windows XP and Windows Vista sometime in the next few months. The changes to the games will be rolled out on a staggered schedule, to be announced closer to the actual update. Microsoft stopped supporting those versions of Windows in 2009 and 2012 respectively, but Blizzard kept up support "since a decent portion of our audience was still using them at the time." But since Windows 7, 8.1 and 10 are now more prevalent, Blizzard is moving to stop enabling those who don't want to make a change.
"After these older operating systems are no longer supported, the games will not run on them, so we encourage any players who are still using one of the older OSes to upgrade to a newer version," Community manager Ornyx said in the forum post.
So if you are still running one of those dinosaur OSes, suck it up and upgrade if you want to keep playing your favorite Blizzard games.
