If you choose to turn on Personalized offers, we will use information about your device and how you use it, including Windows diagnostic data, in combination with your account info and data collected by other Microsoft products and services to offer you personalized tips, ads, and recommendations to enhance your Windows experiences. Personalized offers include suggestions on how to customize and optimize Windows, as well as ads and recommendations for Microsoft and third-party products and services, features, apps, and hardware to enhance your Windows experiences. For example, Windows might tell you about new features to help you get the most out of your device. If you stream movies in your browser, Windows might recommend an app from the Microsoft Store that streams more efficiently. Or, if you are running out of space on your hard drive, Windows might recommend you try OneDrive or purchase hardware to add more storage.
this has been a thing since early 2024.
