Why does Windows Store need the DNS client service to run (Windows 10)?

On my Windows 10 computer (and apparently others), the Windows Store app (or just "Store") will not start if the "DNS Client" is not running - Error "0x80072EE7".



Why?



The "DNS client" service is supposed to only supply DNS caching and name registration.



All other networked applications that I use on Windows 10 seem to work just fine without the DNS Client service, and I never experienced any problems disabling this service before - DNS is just resolved and cached by whatever DNS server/resolver that Windows is configured to use (via DHCP).



This issue is also mentioned at: http://answers.microsoft.com/en-us/windows/forum/windows_10-win_upgrade/app-store-isnt-loading-it-gives-error-0x80072ee7/2455d884-b66c-409b-a288-a5f1cf9aa025?page=2

But with no explanation.



I would like to know this because I generally recommend disabling the DNS Client service in order to make DNS troubleshooting easier (one less cache to worry about).
