World of Warcraft 32-Bit Support Will End When Battle for Azeroth Arrives This Summer

The World of Warcraft game client will no longer support 32-bit operating systems when the Battle for Azeroth expansion goes live on August 14th. Blizzard Entertainment states that the vast majority of players run the game client on 64-bit systems and the change will allow them to focus on the 64-bit version’s stability and efficiency. If you’re using a 32-bit OS, you’ll need to upgrade to keep playing. For most operating systems, this option is available for free.

The memory limitations of 32-bit operating systems can impact the playability and stability of many modern games, and 64-bit operating systems have been industry standard for several years. As with past expansions, we’re making a great many technological updates to WoW with Battle for Azeroth to further enhance the game experience, and the time is right to make this change.

We recommend updating to the 64-bit version of the game before July 1, 2018, to ensure your World of Warcraft gaming experience is unaffected.
