    How to Allow or Deny OS and Apps Access to Contacts in Windows 10


    Windows 10 provides a wealth of data access to make apps useful and valuable to you. These capabilities, which are security constructs that gate access to personal data, include things like Call History, and more. Each capability has its own privacy settings page so that you can control it and what apps and services can use that capability.

    In Windows 10, users can allow or deny apps access to their contacts.

    Starting with Windows 10 build 17063, you can now allow or deny Windows 10 and apps access to contacts on your device (PC) for all users.

    If you allow access, users on your PC will be able to turn on or off if their apps have access to their contacts. If you turn on to let apps access your contacts, you can choose to turn on (allow) or off (deny) access for individual apps.

    This tutorial will show you how to change Privacy settings to allow or deny Windows and apps access to contacts for all users or only your account in Windows 10.

    Deleting contacts from Windows 10


    When you say Windows Mail Live are you referring to Mail app or Windows Live Mail?

    I suggest you to try the steps provided below and check if it helps.


    • Open Windows Live Mail.
    • Press Ctrl + 3 using your keyboard. Right-click on the contact to delete it if it is a single contact.
    • Highlight all contacts by pressing Ctrl + A.
    • Click Delete located on the Ribbon bar.
    • Click OK when you see the message These contacts will also be deleted from Hotmail, Messenger, and other Windows Live services.

    After following the steps above, all your contacts that you have manually added to your account will be deleted however, contacts coming from third-party sites such as Facebook will not be deleted unless you remove Facebook from your account.

    For Mail app:

    Open People app then delete the contact.

    Hope this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.
