When you install a new app in Windows 10 you may see a notification letting you know that you have a new app that can open an application that already has a default file association defined. Below are some examples of how the notifications appear and also two ways to disable these “New App Installed” notifications.

Notification Examples:

OPTION1: Using Group Policy Preferences > Registry

1. Create a new GPO for Group Policy Preferences and give it a descriptive name.
2. Select Computer Configuration > Preferences > Windows Settings > Registry
3. Right-click on Registry and choose New > Registry Item

4. Create the Registry policy item using the values below as a guide.

   Hive: HKEY_LOCAL_MACHINE
   Key Path: SOFTWARE\Policies\Microsoft\Windows\Explorer
   Value name: NoNewAppAlert
   Value type: REG_DWORD
   Value data: 00000001
