Configure App Install Control

App Install Control is a feature of Windows Defender SmartScreen that helps protect PCs by allowing users to install apps only from the Store. SmartScreen must be enabled for this feature to work properly.

If you enable this setting, users will only be able to install apps from the Store.

If you disable this setting, users will be able to install apps from anywhere, including files downloaded from the Internet.

If you do not configure this setting, users will be able to choose their own setting for App Install Control.
