Microsoft has released a holiday advertisement featuring its 'Hey Copilot' voice input and AI capabilities in Windows 11, set to the song A-Punk by Vampire Weekend. The ad showcases family-oriented scenarios, such as syncing Christmas lights to music and navigating assembly instructions with Copilot's assistance, including a cameo from Santa. Viewer reactions have been mixed, with some expressing skepticism about Copilot's capabilities and suggesting humorous voice commands. Concerns have been raised regarding the disconnect between the ad's portrayal of Copilot's functionality and the actual limitations of the technology, particularly its inability to connect smart home devices to a Windows 11 PC. Users appreciate advancements in voice input technology but feel that the advertisement may oversell its current capabilities, leading to potential disappointment.
