Windows provides the following privacy settings to give you control over your privacy.
: The General privacy settings page is being replaced by the Recommendations & offers privacy settings page in more recent versions of Windows 11. If you haven't installed the latest Windows Update, you might still see the General page on your device. If you’re seeing the Recommendations & offers page on your device, see Privacy settings for Recommendations & offers in Windows 11.
Windows generates a unique advertising ID for each user on a device, which app developers and advertising networks can then use for their own purposes, including providing more relevant advertising in apps. When the advertising ID is enabled, apps can access and use it in much the same way that websites can access and use a unique identifier stored in a cookie. Thus, app developers (and the advertising networks they work with) can associate personal data they collect about you with your advertising ID and use that personal data to provide more relevant advertising and other personalized experiences across their apps.
The advertising ID setting applies to Windows apps using the Windows advertising identifier. The advertising ID setting does not apply to other methods of interest-based advertising delivered by Microsoft or third parties, such as cookies used to provide interest-based display ads on websites. Third-party products accessed through or installed on Windows may also deliver other forms of interest-based advertising subject to their own privacy policies. Microsoft delivers other forms of interest-based ads in certain Microsoft products, both directly and by partnering with third-party ad providers.
