Odaily News Microsoft Vice Chairman and President Brad Smith said at a U.S. Senate hearing that an internal ban has been issued, prohibiting all employees from using the DeepSeek app (including desktop/mobile). Although DeepSeek is an open source model and companies can deploy it on their own to avoid data backflow, Microsoft pointed out that it still has the risk of "spreading propaganda or generating unsafe code." It is worth noting that Microsoft has not completely banned competing products (such as Perplexity) in the Windows App Store, but Google applications (including Gemini) have quietly disappeared.
