Announcements Announcements about unload event changes and WIP and MDAG retirement in Microsoft Edge.

Feature Updates Updates to profile setup, third-party sign-in, and password details in Microsoft Edge.

Policy Updates New and updated policies in Microsoft Edge.

Security Stable channel security updates are listed here.

Announcements

• Deprecating the unload event. Microsoft Edge is changing the default behavior of the web platform unload event. As the rollout progresses, pages will no longer run unload event handlers unless the site explicitly permits them.
  • In Edge 152 and 153, unload handlers will stop firing by default for 60% of page loads unless the site explicitly enables them through Permissions Policy.
  • In Edge 154, the rollout will increase to 80% of page loads.
  • In Edge 155, the rollout will reach 100% of page loads.

The unload event is not a dependable way to save data, perform cleanup, or report the end of a session. Browsers and operating systems can suspend or terminate pages without firing it, and this can prevent pages from using the back/forward cache, which may make back and forward navigation slower.

Web developers should migrate to lifecycle events and APIs designed for these scenarios. The long-term direction of the web platform is to remove support for unload.

• Retiring Windows Information Protection (WIP) and Microsoft Defender Application Guard (MDAG) in Microsoft Edge. The WIP and MDAG code paths are being retired from Microsoft Edge, aligning Edge with the Windows platform. Windows deprecated both technologies and removed them in Windows 11, version 24H2.

Only tenants that configured WIP or MDAG in Microsoft Edge are impacted by this change. Both features are off by default and require an admin to turn them on, so tenants that never enabled them are not affected. In practice this is a small, Windows 10 population. Both features were committed for Windows 10 only, and both are already unavailable on Windows 11, version 24H2.

For organizations using WIP, use Microsoft Purview Information Protection, Microsoft Purview endpoint DLP, and Data Loss Prevention and also Intune app protection policies for data protections instead of WIP.

For organizations using MDAG, use the built-in Microsoft Edge for Business security capabilities and Microsoft Edge natively supports hardware isolation instead. Also further, Microsoft Defender SmartScreen, Enhanced Security Mode, Data Loss Prevention, and website typo protection is available.

The change rolls out through the normal Microsoft Edge release channels, and will reach general availability with Microsoft Edge Stable 154 around September 24, 2026.

Feature Updates

• Improved profile setup in the first run experience. Microsoft Edge now includes a close (X) button in the upper-right corner of the new profile setup during the first run experience. When setup is canceled, Microsoft Edge automatically removes the incomplete profile to prevent unused profiles from being retained.
• 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. The feature is available on Windows and macOS devices. Admins can control availability using the NonMicrosoftAccountSignInEnabled policy.
• Enhanced Key Icon with Credential Details, Copy Actions, and Notes. The key icon in Microsoft Edge's address bar now lets users open a detailed panel for any saved credential. From there, users can copy a username, reveal and copy a password, and add personal notes to each login. Users can keep security questions, account purposes, or recovery details with credentials without opening Settings or the full password manager. Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.

Policy Updates

New policies

• AutofillSettings - Block AutoFill data types for specific sites

The unload event is not a dependable way to save data, perform cleanup, or report the end of a session because browsers and operating systems can suspend or terminate pages without firing it. It can also prevent pages from using the back/forward cache, which may make back and forward navigation slower.

Web developers should migrate to lifecycle events and APIs designed for these scenarios. The long-term direction of the web platform is to remove support for unload.

Feature updates

• Tracking prevention when browsing InPrivate. Microsoft Edge is unifying the tracking prevention experience for non-InPrivate and InPrivate browsing windows. The toggle that allowed users to select “Strict” tracking prevention for InPrivate mode is removed. This toggle, previously in edge://settings/privacy/trackingPrevention and on the InPrivate new tab page (NTP), is no longer available. Microsoft Edge now uses the same tracking prevention setting as a normal browsing window when in InPrivate mode.

• Changes to local IP address detection for proxy auto-config (PAC) scripts. Microsoft Edge reports a local network address to proxy auto-config (PAC) scripts through the myIpAddress() and myIpAddressEx() functions. To choose that address, Microsoft Edge connects a UDP socket to a fixed destination address and reports the source address that the operating system selects for that route. Microsoft Edge now uses Chromium's default destinations for this lookup instead of Edge-specific ones: the default IPv4 destination changes from 20.76.201.171 to 8.8.8.8, and the default IPv6 destination changes from 2603:1020:201:10::10f to 2001:4860:4860::8888. The new values are the Google Public DNS addresses that Chromium uses by default. Microsoft Edge sends no packets to these addresses and uses them only so that the operating system selects a route and a source address, so no firewall change is needed.

Because the destination is only a routing sentinel, any host route, policy-based route, or null route that matches it determines which network interface the lookup observes. On a device with more than one active connection, such as a VPN and Wi-Fi at the same time, a route covering the destination can cause a PAC script to receive an address from an unintended network. Organizations should review routes for both the previous and the new destinations. A route that directs the destination to a particular interface causes PAC scripts to observe that interface's address, while a route that leaves the destination unreachable causes Microsoft Edge to fall back to its other address-detection methods.

Administrators who need the lookup to follow a particular network can set a destination that routes over it, using the new PacMyIpAddressIPv4ProbeAddress and PacMyIpAddressIPv6ProbeAddress policies.

• Fading tabs experience retired. The fading tab experience will be removed from the Microsoft Edge browser. The Fade inactive tabs setting will no longer be available in edge://settings/system/managePerformance and users will no longer see tabs fade. Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.

• Summarize videos toggle in YouTube video menu. For eligible Microsoft Edge for Business users, the YouTube video hover overlay now includes a Summarize toggle. Selecting it opens Microsoft 365 Copilot Chat to summarize the video. Availability respects the organization’s Copilot page-context policy, user consent, and data loss prevention protections.

• Update to WebView2 DowngradeVersion policy. The DowngradeVersion policy allows admins to temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version. The DowngradeVersion policy now allows admins to roll back up to four versions (N-1, N-2, N-3, or N-4), which aligns with the Microsoft Edge 2-week release cadence.

Policy updates

New polices

• HttpHeaderInjection - Configure HTTP Header Injection for specific URL patterns
• LaunchEdgeOnWindowsStartupEnabled - Launch Microsoft Edge on Windows startup
• PacMyIpAddressIPv4ProbeAddress - Set the IPv4 route-probe address for PAC scripts
• PacMyIpAddressIPv6ProbeAddress - Set the IPv6 route-probe address for PAC scripts

Obsoleted policies

• CollectionsServicesAndExportsBlockList - Block access to a specified list of services and export targets in Collections (obsolete)
• EdgeCollectionsEnabled - Enable the Collections feature (obsolete)
• RelatedWebsiteSetsEnabled - Enable Related Website Sets (obsolete)
• RelatedWebsiteSetsOverrides - Override Related Website Sets (obsolete)

Web developers should migrate to lifecycle events and APIs designed for these scenarios. The long-term direction of the web platform is to remove support for unload.

• Microsoft Edge has completed the move to a 2-week cadence for updates. We have adopted a new, 2-week release cycle for major versions. For more information, see Faster updates, enterprise-friendly schedule: the new Microsoft Edge release cycle - Microsoft Edge Blog.

Feature Updates

• Automatically unsubscribe users from notifications sent by scam and malicious sites. Microsoft Edge now helps further protect users from malicious web notifications. When a notification leads users to a site that Microsoft Defender SmartScreen blocks as a scam, phishing, or malware page, Edge automatically stops that source from sending users further notifications. Edge lets users know when this happens. Users can review and restore any of these sites anytime under edge://settings/privacy/sitePermissions/allPermissions/notifications.

Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.

• Sign in to Edge with an Apple account. Users can now sign in to Microsoft Edge using an Apple account in addition to the Microsoft account from the profile menu and Edge sign-in screen. Available for Windows and macOS devices. Admins can control availability to this feature using the NonMicrosoftAccountSignInEnabled policy.

Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.

• Real-time video translation retirement. Real-time video translation is being retired through a gradual rollout. Availability may vary across environments during the rollout. The LiveVideoTranslationEnabled policy will be deprecated in a future update.

• Enhanced Key Icon with Credential Details, Copy Actions, and Notes. The key icon in Edge's address bar now lets users click into any saved credential to view a detailed panel. From there, users can copy a username, reveal and copy a password, and add personal notes to each login. Keep track of security questions, account purpose, or recovery details right alongside credentials, without opening Settings or the full password manager.

Note: This is a controlled feature rollout. If you don't see this change, check back as we continue the rollout.

• Drop is retired. We're simplifying Microsoft Edge. Drop is retired in Microsoft Edge version 152.

• New Copilot Cowork policy. Copilot Cowork may perform tasks such as creating tabs, taking screenshots, and interacting with web pages. Admins can now control availability of this feature using the CopilotCoworkToolActionsEnabled policy, which corresponds to the Allow Cowork to take actions on your behalf setting in edge://settings/ai. This policy applies only when Cowork Browsing is enabled at the tenant level in the M365 admin center.

• Clarification of WebView2 DowngradeVersion policy. The DowngradeVersion policy allows admins to temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version (N-1 or N-2). The policy requires an exact 4-part numeric WebView2 Runtime version, for example 151.0.2178.0. Admins can find the exact 4-part version number in the Microsoft Edge release notes for Stable Channel. Major-version-only values are not supported. If no exact matching folder is found, the policy has no effect and the runtime defaults to the BrowserExecutableFolder policy or the Evergreen runtime, which is the default auto-updating runtime.

• Update for LocalNetworkAccessRestrictionsTemporaryOptOut policy. The planned removal of the LocalNetworkAccessRestrictionsTemporaryOptOut policy has been updated. The policy is now scheduled for removal after Microsoft Edge version 156; previously it was version 152.

• Updated Copilot policy. Admins can now control availability of the video transcription feature using the EdgeEntraCopilotPageContext policy, which corresponds to the Allow Copilot to transcribe your video setting in edge://settings/ai.

Release Summary

Announcements

• Microsoft Translator update. On Microsoft Edge versions earlier than 136, translation will stop working after July 30, 2026. Users can update their browser by going to Settings and more (...) > Help and feedback > About Microsoft Edge; install the update and restart when prompted. Admins should update managed devices to the latest version of Microsoft Edge.
• Drop is being retired. We're simplifying Microsoft Edge. Drop will be retired in the near future. Files shared are saved in OneDrive. Text notes need to be downloaded separately.

Feature Updates

• Clipboard suggestions in the address bar. Microsoft Edge can suggest content based on text and links copied to the clipboard directly in the address bar dropdown. Admins can control availability of this feature using the AddressBarClipboardSuggestEnabled policy.
• 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. Admins can control availability to this feature using the PasswordManagerPasskeysEnabled policy.
• Sidebar app list is retired for enterprise users. We're simplifying Microsoft Edge. The sidebar app list is retired for enterprise users. New apps can no longer be added to the sidebar, and apps currently pinned in the app tower are removed. Sidebar app policies are no longer supported, and any configured sidebar app policies are no longer applied. For more information, see Streamline access to your favorite sites and apps with Sidebar in Microsoft Edge.
• Microsoft Edge supported Operating Systems for macOS. Microsoft Edge version 151 or later requires macOS 13 (Ventura) or later.

Fixes

• Fixed an issue which caused third-party extensions to be temporarily disabled on m365.cloud.microsoft.

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

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.

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
