Microsoft Patents Adware Delivery Based on Your Hard Drive Contents:

“The adware framework would leave almost no data untouched in its quest to sell you stuff. It would inspect “user document files, user e-mail files, user music files, downloaded podcasts, computer settings, computer status messages (e.g., a low memory status or low printer ink),” and more. How could we have been so blind as to not see the marketing value in computer status messages?”

The reason Microsoft is falling behind in relevance is because they’re focusing their resources on developing ways to figure out what you want, then trying to sell it to you. Apple focuses on building amazing shit that makes you lust after it, then they tell you where you can pick one up.
