2025-06-07

A blogger discovered that simply viewing the Windows 10 System Settings triggers DNS queries and data transmission to bing.com and cxcs.microsoft.net. Using Nir Sofer's DNSLookupView and TcpLogView, the blogger confirmed that Windows 10 secretly collects user data in the background. The article explores various methods to block this behavior, including modifying router DNS settings, using tools like Pi-hole or NextDNS, and modifying the hosts file. The author ultimately recommends network-wide blocking of www.bing.com and lists other Microsoft domains worth blocking.
