Starting with very first releases of Windows 10, Microsoft was often criticized by a huge number of users, and even by government agencies in certain countries like Netherlands for intensive data collection via the built-in diagnostics and telemetry services. In response, Microsoft has published the list of endpoints Windows 10 connects to after a clean install. Here are the endpoints for the recently released Windows 10 version 1809.
Advertisеment
Having this list in their hands, experienced users and administrators may try to block them by configuring the network so connections to those endpoints can't be established. This method can have a negative effect, as it can break some online functionality of the OS if its backend shares a server with a blocked connection endpoint. Besides telemetry servers, Windows 10 connects to a large number of sites for various purposes, including OneDrive, and Outlook services, Microsoft Store, and Windows Update, and so on.
Microsoft has released details of which endpoints Windows 10 1809 connects to following a clean install. It is a huge list.

Thanks Sergey! Does winaero stop the above via disable telemetry setting?
it should.
