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 revealed 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 new Chromium-based Microsoft Edge web browser. Both are made available to part of the user base when they start to roll out but similarities end here. Microsoft notes: Microsoft Edge builds have features and functionality that are still in development or are experimental. Experiments are like CFR, but the size of the user group is much smaller for testing the new concept. These features are hidden by default until the feature's rolled out or the experiment's finished. Experiment flags are used to enable and disable these features. 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: Get the latest Microsoft Edge policy file from the Microsoft Edge Insider website. It is likely that the policies will become available natively eventually when Edge is released and integrated 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. Consult this Docs 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. 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. Source
Technical Issue during AB-900 Beta Exam - Pearson VUE Queue System Failure - Case #14052082
Hello Support Team, I am writing to request assistance regarding a technical issue I experienced during my AB-900 Beta Exam appointment on January 2nd, 2026. I had a voucher providing an 80% discount valid exclusively for that date. I successfully completed the check-in process on time, and my system passed all pre-exam requirements. However, I was placed in a waiting queue with 24 people ahead of me. After waiting for over 15 minutes, the system displayed a "Reschedule" button. When I clicked it, no dates were available, and I was unable to return to the exam session. I immediately contacted Pearson VUE support via chat. Despite following their instructions to restart the check-in process, the system blocked my access, stating it was past the allowed start time. I opened a formal case with Pearson VUE, and their final resolution (Case #14052082) was that I should reach out to Microsoft Support for further guidance and a "new authorization," as they claimed they could not provide a new voucher for this expired promotion. I prepared extensively for this certification and I was unable to take it due to a failure in the Pearson VUE proctoring queue system. Since the original voucher has now expired, I kindly ask for a new voucher or authorization so I can reschedule and take the AB-900 exam at the discounted rate I previously paid for. Exam: AB-900 Date: January 2nd, 2026 Pearson VUE Case Number: 14052082 Thank you for your time and assistance.PWA shortcuts don't keep asociated with window - Linux
I recently upgraded to version140.0.3485.14 (Official build) beta (64-bit) and noticed that my PWA, even if they open correctly in a independent window, don't show the "running window counter" on the taskbar. So, for example, if a open Outlook, the window open and loads the app, but if a I click the icon again, it opens another window, wich is a little annoying. I tried removing the PWA from Edge, rebooting, and installing again, but didn't work. Because the only change I made is updating Edge, I think is related to this build. (too lazy to go back or install the stable release)
Install Issue - Windows 11 Insider Preview 10.0.26120.2705 (ge_release_upr)
I joined windows insider, and before I start I wanted to note originally only wanted to be in the beta, not the DEV or CANARY builds as I am a beginner. However, at this moment in time, the DEV build downloaded and this build is trying to install, I have clicked download/install multiple times and it takes forever, (I know it takes time but normally is much faster on my device) but when it finally hits 100%, it requests the restart for the update process, whenever my system is rebooted windows update says "Attention Needed" and the install failed. Yet-- when I go to update history this is what shows: Here is what my insider page looks like currently for note: So I am confused and frankly would either like to get this update install gone, or just the beta. Any assistance would be very much appreciated, especially since I am a newbie.Beta channel update to 81.0.416.12 is live
These release notes provide information about new features and non-security updates that are included in the Microsoft Edge Beta Channel. Edge Beta Version 81.0.416.12: February 20 Feature updates Collections is now available. You can get started by clicking the Collections icon next to the address bar. This opens the Collections pane where you can create, edit, and view Collections. We designed Collections based on what you do on the web. If you’re a shopper, a traveller, a teacher or a student, Collections can help. Learn more. Allow the removal (Hide from toolbar) of the Collections button from the Microsoft Edge toolbar for consistency. On-prem Active Directory account auto sign in will only be targeted to organizations that turn it on. If users were already signed in with an on-prem AD account, they will now be able to sign out of it. Now, users will only be automatically signed in with the primary account on their operating system if it is an MSA or an Azure AD account. Admins can enable auto sign in with an on-prem AD account using the ConfigureOnPremisesAccountAutoSignIn policy. Application Guard. Extensions support now available in the container. Added a message to inform users that Internet Explorer is not installed when a user navigates to a page that is configured to open in Internet Explorer mode. Updated the 3D View tool in Microsoft Edge DevTools with a new feature to help debug z-index stacking context. 3D View shows a representation of the DOM (Document Object Model) depth using color and stacking, and the z-Index view helps you isolate the different stacking contexts of your page. Learn more. Localized the F12 Dev tools in 10 new languages, so they will match the language used in the rest of the browser. Learn more. Added support for Dolby Vision playback. On Dolby Vision-enabled Windows 10 Build 17134 (April 2018 Update), websites can show Dolby vision content. See how to enable Dolby Vision content from Netflix. Microsoft Edge can now identify and remove duplicate favorites and merge folders with the same name. To access the tool, click the star on the browser’s toolbar and select "Remove duplicate favorites". You will be able to confirm changes and any updates to your favorites will be synced across devices. We heard from users it can be difficult to distinguish a normal browsing window in dark theme from an InPrivate window since both window frames are dark. The new solid InPrivate blue pill in the top right corner helps reassure users they are browsing InPrivate. Open external links in the correct browser profile. Select a default profile for links opened for external apps to open in from edge://settings/multiProfileSettings. Added a warning to alert users who sign into a browser profile with an account after being previously signed in with another account. This will help prevent unintentional data merging. If you have payment cards saved in your Microsoft account, you can use them in Microsoft Edge while filling out payment forms. The cards in your Microsoft account will sync across desktop devices and the full details will be shared with the website after two-factor authentication (CVC code and your Microsoft identity.) For further convenience, you can choose to securely save a copy of the card on the device during authentication. Line Focus is designed for users who like to focus on a limited part of the content as they read. It lets users keep the focus on 1, 3 or 5 lines at a time and dims out the rest of the page to let users read without distraction. Users can scroll using touch or arrow keys and the focus shifts accordingly. Microsoft Edge is now integrated with Windows Speller on Windows platforms 8.1 and above. This integration provides greater language support, with access to more language dictionaries and the ability to use Windows custom dictionaries. There is no further action needed from the users when a language has been added in the OS language settings and a language spellcheck toggle is enabled in Microsoft Edge settings. When PDF documents are opened using Microsoft Edge, users will now be able to create highlights, change color, and delete highlights. This helps in referencing important parts of the document later, and for collaboration. When loading long PDF documents that have been optimized for web, the pages being viewed by the user will be loaded faster, parallelly, while the rest of the document is loading. Now it's easier to start the Immersive Reader for a website by just pressing the F9 key. Now it's easier to start Read Aloud by using a keyboard shortcut (Ctrl + Shift + U). Policy updates New policies 12 new policies were added. Download the updated Administrative Templates from the Microsoft Edge Enterprise landing page. The following new policies were added. AmbientAuthenticationInPrivateModesEnabled - Enable Ambient Authentication for InPrivate and Guest profiles. AudioSandboxEnabled - Allow the audio sandbox to run.
