The game's support was restarted in March 2016 patch 1.27b from December 2016 is the last patch applicable to the retail version of the game, as all subsequent ones were distributed through exclusively. The initial support cycle lasted until March 2011 with patch 1.26a, during which time the disc check was removed, basic widescreen resolution support was implemented, balancing was refined, new maps and neutral heroes were added, and The Frozen Throne's Rexxar campaign received its second and third acts.

Like prior Blizzard games, both titles were supported simultaneously. They both use the same executable, with Reign of Chaos accessed with the -classic command line argument. The game was released in July 2002, with The Frozen Throne expansion pack following in July 2003. Warcraft III: Reign of Chaos is a fantasy RTS game developed by Blizzard Entertainment with singleplayer and multiplayer content, and is the first fully 3D game by the studio.
