One of the features of Windows 10, is the Windows Store. The Windows Store is a digital distribution platform for Microsoft Windows. It started as an app store for Windows 8 and Windows Server 2012 as the primary means of distributing Universal Windows Platform apps.
As system configurators and administrators, this may be problematic as it introduces new configuration that was not expected or supported by the IT Staff. To mitigate this the following steps can be used to disable the Windows Store.
This can be disabled via local group policy or via active directory domain services group policy.
Type gpedit in the search bar to find and start Group Policy Editor.
In the console tree of the snap-in, click Computer Configuration, click Administrative Templates, click Windows Components, and then click Store.
In the Setting pane, click Turn off Store application and then click Edit policy setting.
On the Turn off Store application setting page, click Enabled, and then click OK.
These policies are applicable to users of the Enterprise and Education editions only. ref: https://support.microsoft.com/en-us/help/3135657/can-t-disable-windows-store-in-windows-10-pro-through-group-policy
