3D Pinball was a space-themed game included in Windows XP since its debut in 1995. It was removed with the launch of Windows Vista due to a bug in the code that caused the game to be unplayable, not because of legal issues as commonly believed. The bug occurred during the transition of Windows XP to 64-bit architecture, where the ball would drop into the launcher and fall through the plunger. Microsoft engineer Raymond Chen, who worked on the project, noted that the original code was largely undocumented, making it difficult to fix. The game was licensed from Cinematronics and Maxis, which limited Microsoft's rights to bundling it within Windows and its Plus! packs, preventing a standalone release. Attempts to revive the game were hindered by these legal constraints. As of 2022, no official version of 3D Pinball has been included in Windows 11, and the licensing situation remains complicated due to the acquisition of Cinematronics and Maxis by Electronic Arts.
