Windows generates a uniqueÂ advertising IDÂ 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.
This tutorial will show you how to enable or disable letting apps use advertising ID for relevant ads for your account or all users in Windows 11.
