Some users may want to know about these URLs to block them right away. A user could block update requests to update Microsoft Edge manually when it is appropriate, or disable the experimentation and configuration service to avoid configuration or functionality changes made by Microsoft.

Microsoft just released preview versions of its Chromium-powered Edge browser today. If you’ve downloaded it to test it, you’ve probably noticed it’s very stable and performs surprisingly well. It even performs better than Google’s own Chrome browser on Windows 10, despite being built on the same Chromium open-source project. While it’s early days for Microsoft’s new Edge, the company has revealed all of the Google services it has replaced or removed from its new Chromium-powered browser to optimize performance.
The rumors keep on coming. After yesterday's rumor that Microsoft is working on Windows Lite, the next attempt at conquering lost territory in the classroom and in education, Windows Central reports that Microsoft will replace Edge on Windows 10 with a Chromium-powered web browser.
