Title

Automatic download of updates from the Windows Store must be turned off. (Cat III impact)

Discussion

Uncontrolled system updates can introduce issues to a system. Obtaining update components from an outside source may also potentially allow sensitive information outside of the enterprise. Application updates must be obtained from an internal source.

Check Content

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\WindowsStore\ Value Name: AutoDownload Type: REG_DWORD Value: 0x00000002 (2)

Fix Text

Windows 8.1 split the original policy that configures this setting into two separate ones. Configuring either one to "Enabled" will update the registry value as identified in the Check section. Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Store >> "Turn off Automatic Download of updates on Win8 machines" or "Turn off Automatic Download and install of updates" to "Enabled".
