Hi Louis Santini,
To fix the issue, please follow the steps listed below.
Optimize Internet Explorer settings :
http://windows.microsoft.com/en-US/hotmail/optimize-internet-explorer .
You can also try
Reset the configuration for MSN:
1. Sign out of MSN
2. Open MSN but do not sign in
3. Press CTRL SHIFT and F11 together. When done correctly, you'll get a pop up for removing account
4. Proceed to remove account
5. Start MSN again and enter the needed information.
Then Run MSN again and check out if it still defaults the weather content to that city.
Thanks,
Nitesh
