Blizzard will start dropping support for Windows XP and Windows
Vista beginning later thins year. Here's the plan:
Starting later this
year, we will begin the process of ending support for Windows XP and Windows
Vista in World of Warcraft, StarCraft II, Diablo III, Hearthstone, and Heroes of
the Storm. Microsoft ceased mainstream support for these versions of Windows in
2009 and 2012, respectively, but since a decent portion of our audience was
still using them at the time, we continued supporting them. However, there have
been three major Windows releases since Vista, and at this point, the vast
majority of our audience has upgraded to one of the newer versions.
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. We’ll be rolling out this change on a
staggered schedule, and will post further notices as we get closer to making the
change for each game.
