How to Allow or Deny OS and Apps Access to Messaging 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 Calendar, Contacts, 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 read and send messages via text or MMS (aka: "Messaging").

Starting with Windows 10 build 17063, you can now allow or deny Windows 10 and apps access to messaging 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 messaging. If you turn on to let apps access messaging, 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 messaging for all users or only your account in Windows 10.
