Once the group policy editor opens, navigate to the key User Configuration-> Administrative Templates-> Windows Components-> Store
On the right panel, you can see the option- Turn off the store application. Double click on this entry and you can see the option to disable it. Select “Enabled” from the list and save it.
If you enable the settings, the access to store application is denied and you cannot install any apps from the store. Users will get an error message when they try to access it.
