Since the release of Windows 10, Microsoft has been accused of breaching privacy and connecting users to services without proper disclosure. The company now has released a list of websites and services that a Windows PC connects to after a clean install.

The list mostly consists of Microsoft services which provide data endpoints to the respective Microsoft apps. The list can be derived after installing Windows 10 (1709 or above) and leaving the PC idle on default settings for a week. This can then be used to Compile reports on traffic going to public IP addresses. However, if you don’t want to go through all that then you can head below to take a look at the list.

Apps

Weather app Live Tile. If you turn off traffic to this endpoint, no Live Tiles will be updated.
