I signed into Seven and ran Speed Test. Lemme tell you, I get GREAT speeds for a guy who lives in Helena State Forest (about a mile off of Grizzly Gulch Road! heh.). Then I found the window A Guy posted, added my zip code and ran Speed Test again... I am back home in New Jersey. Finally!
Signed back into Eight and ran Speed Test once again. Somehow my NJ location stuck... at least for the test. My Map App is still wrong however.
On the snip I posted there is something called Windows Location platform. I'll have to track that down and see what's there.
