But the real PSA here, kids, is that it’s time to upgrade your OS if you’re still using Windows XP or Vista. Like, for reals. And not just because you won’t be able to play World of Warcraft, Diablo III, Starcraft 2, Hearthstone or Heroes of the Storm on your Pentium II anymore, but because Windows XP has been out for 15 years, and you shouldn’t have installed Windows Vista in the first place. And, you know, it’s probably also time to upgrade that Pentium II.

“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,” Blizzard explains. “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.”

Kiss them goodbye. They’ve had a good run. Except Windows Vista, which never actually ran. I’m here all week.
