[QUOTE="oldschool, post: 851517, member: 71262"] by [URL='https://www.ghacks.net/author/martin/']Martin Brinkmann[/URL] on January 01, 2020 Browsers like Firefox, Chrome or Microsoft Edge come with built-in functionality to run experiments. Browser makers like Mozilla or Google may enable or disable features or changes in select browsers; this is often used to A-B test features or get early feedback on new implementations. While most users may not even notice that experiments are running in their browsers, it happened in the past that experiments caused issues. The latest case was [URL='https://www.zdnet.com/article/google-chrome-experiment-crashes-browser-tabs-impacts-companies-worldwide/']revealed[/URL] in November when administrators from around the world reported that a Chrome experiment would crash browsers in organizations worldwide. Negative side-effects of experiments are a problem for home users and business users alike, and it is often desirable to disable or block experiments from being downloaded and run. Microsoft distinguishes between controlled feature rollouts and experiments in the company's [URL='https://www.ghacks.net/2019/03/25/this-is-the-chromium-based-microsoft-edge-browser/']new Chromium-based Microsoft Edge web browser[/URL]. Both are made available to part of the user base when they start to roll out but similarities end here. Microsoft notes: System administrators may use the "Control communication with the Experimentation and Configuration Service" on pro and Enterprise editions of Windows 7, 8.1 or 10 to prevent experiments in the browser. Here is what is needed for that: [LIST=1] [*]Get the latest [URL='https://www.microsoftedgeinsider.com/en-us/enterprise']Microsoft Edge policy file[/URL] from the Microsoft Edge Insider website. It is likely that the [URL='https://www.ghacks.net/2019/06/21/microsoft-releases-microsoft-edge-chromium-group-policies-preview/']policies will become available[/URL] natively eventually when [URL='https://www.ghacks.net/2019/11/04/microsoft-plans-to-release-the-new-microsoft-edge-on-january-15-2020/']Edge is released and integrated[/URL] in Windows. [*]Extract the file (first a cab, then a zip). [*]Open Windows > Admx. [*]Copy the two .admx template files to C:\Windows\PolicyDefinitions\. [*]Open the language folder that matches the system language and copy the .adml files to the corresponding language folder of C:\Windows\PolicyDefinitions\ [*]Open Start, type gpedit.msc and hit the Enter-key to open the Group Policy Editor. [URL='https://docs.microsoft.com/en-us/DeployEdge/configure-microsoft-edge']Consult this Docs[/URL] page on the Microsoft website for additional scenarios, e.g. when domain controllers are used. [*]Open Computer Configuration > Administrative Templates > Microsoft Edge. [*]Open the policy "Control communication with the Experimentation and Configuration Service" policy. [*]Set the policy to Enabled. [*]Set it to either "Retrieve configurations only" or "Disable communication with the Experimentation and Configuration Service". Retrieve will download configuration payloads only, disable won't download or enable them. [/LIST] The behavior of not configuring the policy differs depending on whether it is a managed or unmanaged device. Managed devices will download the configuration only while unmanaged devices will retrieve configurations and experiments.
