While there are probably aren't many people who are still using Windows XP and Vista to play Blizzard's games, those who us the said OS will certainly need to upgrade their operating system to at least Windows 7. Blizzard recently announced on its forum that they will be discontinuing support for the two operating systems in World of Warcraft, Starcraft 2, Diablo 3, HearthStone and Heroes of the Storm. The community manager Ornyx stated that Starting later this year, they will begin the process of ending support for Windows XP and Windows Vista in the mentioned list of games.
Microsoft dropped support for Windows XP and Vista in 2009 and 2012, but the community manager Ornyx says that because a decent portion of its player base was still playing games on them, Blizzard's support continued. However, Ornyx pointed out that a vast majority of Blizzard's audience has now upgraded to either Windows 7, Windows 8, or Windows 10. This only means for players who are using Windows XP and Vista, it is time to upgrade their operating system.
Ornyx also stated that after these older operating systems are no longer supported, the games will not run on them, so they encourage players who are still using one of the older Operating systems to upgrade to a newer version.
It's a good thing that Blizzard supported these operating systems for this long, but users expressed their upset by this news. Players may know how games like World of Warcraft and Hearthstone to be played in their most comfortable or familiar Operating System, and that may be XP or Vista. Hopefully,fans can upgrade and continue enjoying Blizzard's games.
