Microsoft uses two main distribution channels for its Windows operating system - individual sales and bundling Windows with PCs. While individual sales can lead to piracy issues, it also expands the user base. Bundling Windows faces legal issues but is very effective. For its Live Search product, Microsoft relies on distributing through its own products and services to lock in users, but the product itself is weak. Overall, Microsoft has strong distribution but needs to focus on improving product quality to solidify its position over the long run.
