  • Fixed issue in location that caused navigation apps to lag behind user’s actual location.
  • Improved performance of loading webpages in Internet Explorer 11 when roaming user profiles are used.
  • Fixed issue that caused phones to stop ringing from an incoming call, if interrupted by an SMS.
  • Fixed issue that caused some phones to be unable to re-add a primary Microsoft account without resetting after upgrading from Windows Phone 8.1.
  • Fixed additional issues with Microsoft Edge, Internet Explorer 11, Bluetooth, Cortana, Wi-Fi, Windows Camera app, revised daylight saving time, USB, TPM, Graphics, Group Policy, downloading music or movies purchased through the Windows Store, Network Diagnostics and Windows Explorer.
