Overview​

This script blocks servers that update offline maps 1 2 and provide Bing Maps APIs for geospatial 3 and location services 4 5. This action enhances privacy by preventing the transmission of your location data to Microsoft.

Caution

This script has potential side effects:

  • Impacts apps and websites using Bing Maps for location services, including third-party ones.
  • Disables offline map updates 1 2, potentially leading to less accurate and outdated maps.

Blocked Hosts​

The blocked hosts are:

  • maps.windows.com 1 2
  • dev.virtualearth.net 2 4 6
  • ecn.dev.virtualearth.net 1 2 3
  • ecn-us.dev.virtualearth.net 1 6
  • weathermapdata.blob.core.windows.net 1

The following hosts are excluded (not blocked):

  • r.bing.com 6 7 8: Blocking this host impacts several features, including Cortana 1 2, Live Tiles 1 2, Copilot 9 10 11, and Bing Maps 6 7 8.
  • ssl.bing.com 2: This host is not only associated with Maps but also other functionality such as viewing and deleting search history for your privacy 12 and Bing Webmaster APIs 13.
Use with Caution

This script is only recommended if you understand its implications.

Some non-critical or features may no longer function correctly after running this script.

This script can be fully reversed to restore changes if something goes wrong.
