Download the latest .ADMX template for Windows 10 via the link shared by Mike above, then overwrite your existing templates with the newer ones.
The specific policy settings are under:
Computer Configuration -> Administrative Templates -> Windows Components -> Search ->
Allow Cortana
Computer Configuration -> Administrative Templates -> Windows Components -> Store ->
Disable all apps from Windows Store/Turn off the Store application
Hope this helps.
