How to Choose Where Apps can be Installed from in Windows 10

information   Information
Starting with Windows 10 build 15042, you can choose where apps can be installed from.

This Application Installation Control feature has been officially announced starting with Windows 10 build 15046.
  • Allow apps from anywhere - Users will be able to install both desktop and Store apps without getting a message dialog.
  • Warn me before installing apps from outside the Store - Users will be able to install both desktop and Store apps. Users will get a "The app you're installing isn't from the Windows Store" message dialog when trying to install a desktop app to see if they want to visit the Store for more apps.
  • Allow apps from the Store only - Users will only be able to install apps from the Store. If users try to install a desktop app, they will get a "You can only install apps from the Windows Store" message dialog to visit the Store for more apps. Limiting installations to apps from the Store helps to keep you PC safe and reliable. Users will still be able to run desktop apps that were previously installed.

This tutorial will show you how to choose where apps can be installed from for all users in Windows 10.

You must be signed in as an administrator to be able to choose where apps can be installed from.
