Some apps or games in Microsoft Store are designed to take advantage of specific hardware or software capabilities on your Windows device. A photo app might need to use your phone's camera, or a restaurant guide might use your location to recommend nearby places.
In Windows 10, use the Privacy page to choose which apps can use a particular feature. Select Start > Settings > Privacy. Select the app (for example, Calendar) and choose which app permissions are on or off.
The Privacy page won't list apps with permission to use all system resources. You can't use the Privacy settings to control what capabilities these apps can use. Windows Desktop apps fall under this category.
To see the permissions for an app, go to the app product page in Microsoft Store or online. If you don’t want an app to use any of the features listed, you can choose not to install it.
