Dave Plummer, the creator of the Windows Task Manager and Pinball game, has expressed concerns about Windows 11, criticizing Microsoft's focus on integrating new artificial intelligence features at the expense of system stability. He argues that stable releases should prioritize fixing critical bugs over adding new functionalities. Plummer references the period around Windows XP Service Pack 2, when Microsoft halted new feature introductions to enhance security and stability in response to major security threats. He advocates for a similar approach for Windows 11, urging Microsoft to pause feature additions until the system is stabilized and existing issues are resolved. Plummer emphasizes the need for Microsoft to focus on improving user experience by prioritizing fixes over new features, particularly for power users.
