Manage Windows 10 connection endpoints

Applies to

  • Windows 10, version 1709 and later

Some Windows components, app, and related services transfer data to Microsoft network endpoints. Some examples include:

  • Connecting to Microsoft Office and Windows sites to download the latest app and security updates.
  • Connecting to email servers to send and receive email.
  • Connecting to the web for every day web browsing.
  • Connecting to the cloud to store and access backups.
  • Using your location to show a weather forecast.

This article lists different endpoints that are available on a clean installation of Windows 10, version 1709 and later. Details about the different ways to control traffic to these endpoints are covered in Manage connections from Windows operating system components to Microsoft services. Where applicable, each endpoint covered in this topic includes a link to specific details about how to control traffic to it.

We used the following methodology to derive these network endpoints:

  1. Set up the latest version of Windows 10 on a test virtual machine using the default settings.
  2. Leave the devices running idle for a week (that is, a user is not interacting with the system/device).
  3. Use globally accepted network protocol analyzer/capturing tools and log all background egress traffic.
  4. Compile reports on traffic going to public IP addresses.
  5. The test virtual machine was logged in using a local account and was not joined to a domain or Azure Active Directory.

Note

Microsoft uses global load balancers that can appear in network trace-routes. For example, an endpoint for *.akadns.net might be used to load balance requests to an Azure datacenter, which can change over time.
