This document discusses Microsoft's distribution channels for two products: the Windows operating system and the Live Search search engine. For Windows, the document analyzes its distribution through both individual sales and bundled sales with hardware purchases. It notes that bundled sales, though illegal, represent the majority of Windows distribution. This channel faces weaknesses like new low-cost competitors but provides Microsoft strong lock-in effects. For Live Search, the document briefly introduces the search engine and notes it uses different distribution channels than competitors like Google.
