Windows 10: Stop Apps From Reading Your Messages

Windows 10 apps can request access to your text messages, and if you grant it, they can read and send SMS through your PC. This guide shows you how to revoke that permission and block apps from accessing your messages, protecting your privacy and keeping your conversations secure. You’ll need to be signed in as an administrator to change these settings.

What You’ll Need

• An administrator account on Windows 10
• Your PC must be running Windows 10 version 1803 or later (the messaging permission settings are available in these versions)

Step-by-Step

1. Open Windows Settings. Click the Start button (Windows logo) in the bottom-left corner, then click the gear icon (Settings). Alternatively, press Windows + I on your keyboard.
2. Go to Privacy. In the Settings window, click the Privacy tile (it has a lock icon).
3. Select Messaging. In the left sidebar, scroll down and click Messaging under the “App permissions” section.
4. Turn off global access. At the top of the Messaging settings page, you’ll see “Allow apps to access your messages.” Toggle this switch to Off. This blocks all apps from reading or sending messages on your device.
5. Review individual app permissions. Below the global toggle, you’ll see a list of apps that have requested message access. Each app has its own toggle. If you want to allow only certain apps, keep the global toggle on and turn off the toggles for apps you don’t trust. If you turned the global toggle off, these individual toggles are grayed out and cannot be changed.
6. Check for legacy apps. Some older desktop apps (not from the Microsoft Store) may not appear in this list. To block those, you’ll need to check their own settings. Look for a “Messaging” or “SMS” permission within the app’s options and disable it.

Common Mistakes

• Turning off only the global toggle and thinking it’s enough: This does block all apps, but if you later turn it back on, all previously allowed apps will be re-enabled. You must also manually turn off each app you don’t want.
• Ignoring the “Allow apps to access your messages” toggle: Some users only disable individual app toggles, but if the global toggle is on, new apps can still request access and you’ll get a prompt. To be safe, turn off the global toggle.
• Forgetting about phone link apps: Apps like “Your Phone” (now “Phone Link”) rely on message access. If you want to block messages entirely, you must disable this app too, or it will continue to sync messages.
• Not restarting the app: After changing permissions, some apps may still show old messages until you restart them. Close and reopen the app to apply the changes.

Tips

• Use the global toggle as a master switch. If you’re not sure which apps need message access, turn off the global toggle and then turn it on only when you need it. This minimizes the window of exposure.
• Regularly review app permissions. Every few months, go back to Settings > Privacy > Messaging and check which apps have access. Revoke any that you no longer use or trust.
• Be cautious with app requests. When an app asks for message access, consider whether it truly needs it. A messaging app might, but a weather app definitely doesn’t. Deny access by default.
• Use a standard account for daily use. If you use an administrator account, any app you run has more privileges. Create a standard user account for everyday tasks to reduce the risk of apps gaining unwanted permissions.
• Keep Windows updated. Microsoft regularly updates privacy settings and security features. Ensure your Windows 10 is up to date to have the latest controls.

Troubleshooting

I don’t see the Messaging option in Privacy settings. This usually means you’re running an older version of Windows 10. Go to Settings > Update & Security > Windows Update and install all pending updates. The Messaging permission was introduced in version 1803.

An app still shows my messages after I disabled access. First, restart the app. If that doesn’t work, the app may have cached messages locally. Clear the app’s cache or data (in Settings > Apps > [App name] > Advanced options > Reset). For desktop apps, check the app’s own settings for a sync or message storage option.

The toggles are grayed out. This happens when the global “Allow apps to access your messages” is off. Turn it back on to adjust individual app toggles, then turn off the ones you don’t want, and finally turn the global toggle back off if you want to block all.

I turned off access, but I still get notifications from messages. Notifications are separate from message access. If you want to disable message notifications, go to Settings > System > Notifications & actions, and turn off notifications for the specific messaging app or for all apps.

My phone is still syncing messages to my PC. This is likely due to the “Phone Link” (formerly “Your Phone”) app. Open the Phone Link app, go to Settings, and toggle off “Messages” or “Sync messages.” You can also unlink your phone entirely from the app.

Frequently Asked Questions

Q: Can I block all apps from accessing messages at once?
A: Yes, turn off the “Allow apps to access your messages” toggle at the top of the Messaging settings page. This blocks all apps, including future ones.

Q: Will this stop my PC from receiving text messages?
A: No, it only stops apps from reading and sending messages. You can still receive messages if you have a messaging app that works independently, but it won’t have access to your SMS.

Q: What about apps that are not from the Microsoft Store?
A: These apps may not appear in the list. You’ll need to check their own settings for message access or uninstall them if you don’t trust them.

Q: Does this affect my ability to send messages from my PC?
A: Yes, if you disable message access, apps that rely on it (like Phone Link) will no longer be able to send or receive SMS through your PC. You’ll need to use your phone directly.

Q: How do I know which apps have access to my messages?
A: Go to Settings > Privacy > Messaging. The list of apps under the global toggle shows which apps have requested and been granted access.

Q: Can I allow a specific app while blocking others?
A: Yes, keep the global toggle on, and turn off the toggles for every app except the one you want to allow. This gives you granular control.
