  • Switching Costs
  • Scale Advantages
  • Network Effects
  • Brand
  • Proprietary Technology
  • Ecosystem Lock-in
  • Distribution

Microsoft’s competitive moat is primarily driven by high switching costs, economies of scale, and strong ecosystem/network effects across Windows, Office/Microsoft 365, Azure, and enterprise agreements. Its brand, proprietary technology/IP, and broad distribution further reinforce customer lock-in and durable pricing power.
