Announcements

• Microsoft Edge supported operating systems for macOS. Microsoft Edge version 150 is the last release that supports macOS 12 (Monterey). Microsoft Edge version 151 or later requires macOS 13 (Ventura) or later. For more information, see Microsoft Edge supported operating systems.
• Migration to improved V2 architecture for Workspaces. Workspaces, introduced in Edge in 2022, allows users to create durable sets of tabs that can be saved and shared with others. In order to improve reliability and performance of this feature, the following changes are being made:
  • Migrating data for saved Workspaces from OneDrive/SharePoint to Edge Sync service
  • Removing the collaboration/share functionality of this feature

For organizations who have disabled Sync through policy, the existing v1 Workspace data will still be migrated to the new architecture. New v2 Workspaces created after migration won't sync across devices and will remain local to each device. This update occurs on a progressive rollout beginning in Edge Stable v145 and continues rolling out through Edge v150. For more information, see Getting started with Microsoft Edge Workspaces.

• Sidebar app list is being retired. We're simplifying Microsoft Edge. The sidebar app list will be retired in the near future. New apps can no longer be added to the sidebar, and apps currently pinned in the app tower will be removed in a future update. Sidebar app policies will no longer be supported, and any configured sidebar app policies will no longer be applied. For more information, see Streamline access to your favorite sites and apps with Sidebar in Microsoft Edge.

Feature Updates

• Clarify choices surrounding third-party cookie settings. Language under 'Settings > Privacy, search, and services > Cookies' is updated to better describe the choices users have when managing third-party cookies.
• Sign in to Edge with a Google account. Users can now sign in to Microsoft Edge using a Google account in addition to a Microsoft account from the profile menu and Edge sign-in screen. Available for Windows and macOS devices. Admins can control availability of this feature using the NonMicrosoftAccountSignInEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• Intune MAM Protected Downloads. The protected downloads feature for Intune MAM now saves downloaded files to the 'Documents > Microsoft Edge > Downloads' folder in OneDrive.
• Enterprise WebView2 runtime downgrade via DowngradeVersion policy. Starting with Microsoft Edge version 150, enterprises can actively use the 'DowngradeVersion' policy to downgrade WebView2 applications. Administrators can temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version (N-1 or N-2) using the new 'DowngradeVersion' policy in msedgewebview2.admx. The policy allows enterprises to mitigate critical regressions by specifying per-application executable-to-version mappings. The Edge Updater installs the target version side-by-side, and the WebView2 Loader redirects targeted applications accordingly. Downgrades automatically expire with each new WebView2 release. Applications pinned to N-1 remain on the same version (now becoming N-2) and automatically update in the next release, while applications pinned to N-2 revert to the current Evergreen Runtime. The policy applies only to enterprise-managed devices (domain-joined or MDM-enrolled). For more information, see Microsoft Edge WebView2 Policy Documentation.
• Update to the "View in File Explorer" feature. When the ConfigureViewInFileExplorer policy is enabled, the View in File Explorer feature can be used in SharePoint document libraries. Microsoft Edge has updated the feature to enforce additional validation and restrictions when triggered by webpages to improve security.
• Security Update Alerts in the Edge management service. Administrators can choose a severity threshold and receive alerts when a new Microsoft Edge update includes security fixes that meet or exceed that level, including zero-day fixes. This helps organizations quickly identify updates that may require attention while avoiding unnecessary notifications for routine releases. Note: This experience is in public preview and is available by opting in to Targeted Release in the Microsoft 365 admin center. For more information, see Monitoring dashboard.

Policy Updates

New policies

• AllowSocketPoolSizeRandomizationForProxies - Allow socket pool size randomization for proxies
• NonMicrosoftAccountSignInEnabled - Enable sign-in to Microsoft Edge using non-Microsoft accounts
• StrictMimetypeCheckForWorkerScriptsEnabled - Enable strict MIME type checking for worker scripts

Note

For the latest web platform features and updates, see the Microsoft Edge 150 web platform release notes (Jul. 2026).

Fixes

• Fixed an issue that prevented QR code generation from working.

Feature updates

• Intune MAM Protected Downloads. The protected downloads feature for Intune MAM will now save downloaded files to the Documents > Microsoft Edge > Downloads folder in OneDrive.
• Extensions monitoring in the Edge management service. The Microsoft Edge management service now allows admins to gain visibility into extensions installed across their managed users. From the extensions monitoring page, admins can see which extensions have been installed as well as manage user requests for blocked extensions. For more information, see Microsoft Edge Extensions Monitoring.
• Validate Edge builds early with enterprise preview. Enterprise preview provides a simpler way for admins to flight pre-release Edge builds to their users. To reduce friction and bolster usage, users will receive pre-release builds directly inside of their Stable Edge application. Admins can allow users to easily opt-out of the preview experience, using built-in rollback to switch between their pre-release and stable channels with ease. Microsoft 365 admin center users can configure the feature, view their flighting population, and receive personalized recommendations all in one place. For more information, see Get started with Enterprise Preview in Microsoft Edge.

  • Migrating data for saved Workspaces from OneDrive/SharePoint to Edge Sync service

    For organizations who have disabled Sync through policy, the existing v1 Workspace data will still be migrated to the new architecture. New v2 Workspaces created after migration won't sync across devices and will remain local to each device. This update occurs on a progressive rollout beginning in Edge Stable v145 and will continue rolling out in Edge v149. For more information, see Getting started with Microsoft Edge Workspaces.

Feature Updates

• Passkey Sync for Enterprise Users. Microsoft Edge is introducing support for passkey synchronization for enterprise users, enabling secure, passwordless authentication across devices. Passkeys created in Edge can now be synced seamlessly, improving sign-in experience while maintaining strong security standards. Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.
• Enterprise WebView2 runtime downgrade via DowngradeVersion policy. Administrators can temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version (N-1 or N-2) using the new DowngradeVersion policy in msedgewebview2.admx. The Downgrade Version policy allows enterprises to mitigate critical regressions by specifying per-application exe-to-version mappings. The Edge Updater installs the target version side-by-side, and the WebView2 Loader redirects targeted apps accordingly.

Downgrades auto-expire with each new WebView2 release: apps pinned to N-1 remain on the same version (now becoming N-2) and will auto-update in the next release, while apps pinned to N-2 will revert to the current Evergreen version. The policy applies only to enterprise-managed devices (domain-joined or MDM-enrolled). For more information, see Microsoft Edge WebView2 Policy Documentation | Microsoft Learn.

• Collections retirement. Collections have been removed in this update. Users can no longer access or use the feature. To keep saved content, users can export it, or move all pages to Favorites before updating to Microsoft Edge Stable 149. For more information, see Organize your ideas with Collections in Microsoft Edge - Microsoft Support.
• Modern, unified, and updated Look and Feel. Microsoft Edge has updated the Look and Feel to give customers a unified experience across all of Microsoft AI surfaces including Copilot and Bing. This changes multiple elements of the UX such as spacing, corners, fonts, default colors, etc.
• Custom primary password retirement. Users are no longer able to create a new custom primary password in Edge Settings edge://settings/autofill/passwords/settings. Any users who are still using a custom primary password is automatically migrated to device authentication. Additionally, the PrimaryPasswordSetting policy will no longer support the WithCustomPrimaryPassword option. For more information, see Keep your saved passwords private in Microsoft Edge | Microsoft Support.
• Unifying Copilot Chat policy controls. The Microsoft365CopilotChatIconEnabled policy is the standard for configuring Copilot Chat. Previously, this behavior was controlled by blocking the Copilot extension, either explicitly or by using the * wildcard via the ExtensionSettings or ExtensionInstallBlockList policies. Extension and sidebar policies no longer affect the appearance or functionality of Copilot Chat. Copilot address bar suggestions were also tied to extension policy settings. Starting in Microsoft Edge version 149, admins can use the CopilotAddressBarSuggestionsEnabled policy to manage this behavior.
• Intune MAM Protected Downloads. The protected downloads feature for Intune MAM is now available for BYOD (Bring Your Own Device) devices, which aren't managed by a tenant.

Policy Updates

New policies

• AllowSocketPoolSizeRandomizationForProxies - Allow socket pool size randomization for proxies
• NonMicrosoftAccountSignInEnabled - Enable sign-in to Microsoft Edge using non-Microsoft accounts
• StrictMimetypeCheckForWorkerScriptsEnabled - Enable strict MIME type checking for worker scripts

Note

Feature Updates

• Browsing with Copilot Public Preview now open for signups. We're excited to announce that the Limited Public Preview for browsing with Copilot in Edge for Business is now open for admin signups. Browsing with Copilot introduces agentic browsing to the enterprise, allowing Copilot to navigate websites, fill in information, and complete multi-step tasks on behalf of users. This helps employees offload repetitive browser work and move faster from information to action, all within a managed, secure environment. Admins can now request access to the preview in this form and start bringing Browsing with Copilot to their organization.

• Update to the AutoplayAllowed policy. The AutoplayAllowed policy behavior has been updated. In Microsoft Edge versions 92 through 145, setting the policy to Disabled configured media autoplay to "Limit." In versions 146 and 147, setting the policy to Disabled configured media autoplay to "Block." In version 148 and later, when the policy is set to Disabled, Edge once again sets media autoplay to "Limit." The "Limit" setting restricts autoplay to sites with high media engagement and active WebRTC streams.

This update occurs on a progressive rollout beginning in Edge Stable v145 and will continue rolling out in Edge v148. For more information, see Getting started with Microsoft Edge Workspaces.

• Microsoft 365 Copilot Chat. The Edge internal container page that hosts compliant M365 Copilot chat in the sidebar has been updated. Blocking internal edge:// or chrome-untrusted:// URLs isn't recommended as this may lead to unexpected errors and will disable the Microsoft 365 Sidebar Copilot Chat experience. For more information, see Allowlist for Microsoft Edge endpoints.

Feature Updates

• M365 Copilot Search relevance using work browsing history. With admin approval, Microsoft Edge can now send selected work-related browsing history from third-party apps to Microsoft 365 Copilot to improve search result ranking. When a user searches on Microsoft 365 Copilot Search, M365 Copilot will also surface results from work browsing history when relevant, helping users find recently visited work pages faster. Admins can control availability of this feature using the ShareBrowsingHistoryWithCopilotSearchAllowed policy.
• Password affiliation service. Password autofill suggestions in Edge are currently based on top-level domain matching, which means the same credentials can be suggested on sites like account.microsoft.com and office.microsoft.com. With this feature, Edge groups related domains together across various desktop and mobile properties called affiliations. When a customer visits a URL, the Edge client will query the affiliations backend to obtain "affiliated groups" for that URL. The process involves sending a hash of the visited URLs to the service, which then returns a list of affiliated URLs and ensures that the relevant credentials will be displayed in the autofill suggestions across affiliated domains. Admins must use both the PasswordManagerEnabled and PrimaryPasswordSetting policies together to control access to this feature. Configuring both policies allow admins to ensure no passwords get saved, lookups for autofill are disabled and affiliation endpoint won't be queried.
• Copilot New Tab Page. Search, chat, and explore the web from one search box with Copilot suggested actions and curated work content to help your users get things done faster on the new, refreshed Copilot New Tab Page. Users can also view personalized news and activities. Admins can control availability to this feature using the CopilotNewTabPageEnabled policy. For more information, see Configure the Copilot new tab page.
• Shadow AI. Currently admins can set Purview DLP policies to protect sensitive data from being sent to any Generative AI apps, users get blocked from sending their prompts to LLM when this is triggered and stops their workflow. This new add-on to the feature shows a new UI that will give users the option to be redirected to M365 Copilot which will open and navigate to this M365 Copilot tab and allow them to send the same prompt there.
• Enhanced Autofill. For desktop users, Microsoft Edge can now autofill additional document types-including passports, driver's licenses, and other specialized forms-on top of your saved addresses. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• Allow M365 authentication popups in work profiles. When users are signed in with a work account, some Microsoft 365 sites (for example, microsoft.com, cloud.microsoft, and microsoft365.com) may open authentication pop-up windows to Microsoft sign-in endpoints such as login.microsoftonline.com, login.live.com, or login.microsoft.com. These pop-ups are required to complete sign-in. Microsoft Edge now allows authentication pop-up windows from Microsoft first-party services by default. Admins can control availability to this feature using the M365AuthPopupsInWorkEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• Updated AI settings page. Settings for Copilot features now are housed under one AI settings page to create a cohesive setting experience. Existing admin controls and policy configurations continue to apply.

Policy Updates

New policies

• CopilotAddressBarSuggestionsEnabled - Enable Copilot address bar suggestions
• CpuPerformanceTierOverride - Override for the CPU performance tier
• DataUrlInWebWorkerOpaqueOriginEnabled - Enable opaque origins for data URLs in Web Workers
• DefaultLocalFontsSetting - Default Local Fonts permission setting
• ForceForegroundPriorityForUrls - Force foreground priority for specific URLs
• LocalFontsAllowedForUrls - Allow Local Fonts permission on these sites
• LocalFontsBlockedForUrls - Block Local Fonts permission on these sites

Deprecated policies

• ForceForegroundPriorityForUrls - ForceForegroundPriorityForOrigins is renamed to ForceForegroundPriorityForUrls
• OnSecurityEventEnterpriseConnector - Add macOS platform support
• ProtectedContentIdentifiersAllowed - Remove macOS platform support
