Feature updates

• Use Primary work profile as default profile to open external links. Microsoft Edge currently opens external links using the “Last Used” profile by default. While for enterprise users, the Primary Work Profile (signed in with a Microsoft Entra ID for enrolling the device) is normally the best profile for opening external links. With this feature, for Windows, Edge checks if the Primary Work Profile exists and makes it the default profile for opening external links if available. For Mac and Linux, if only one work profile signed in with a Microsoft Entra ID account is found, it’s treated as the Primary Work Profile. Admins can control availability to this feature using the EdgeOpenExternalLinksWithPrimaryWorkProfileEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• New Autofill Personal Information Settings Configuration. A web form field collection consent toggle will be available in Autofill settings (edge://settings/autofill/personalInfo). This allows users to consent to Microsoft Edge collecting web form field labels (for example, "First Name," "Email") to improve Autofill suggestion accuracy. Only field labels are collected and not user-entered data. The web field labels are stored securely per Microsoft's privacy standards.
  This new setting is manageable via existing policies in Autofill (for example, AutofillAddressEnabled, EdgeAutofillMlEnabled. AutofillAddressEnabled) is the parent setting for (EdgeAutofillMlEnabled)[/deployedge/microsoft-edge-browser-policies/edgeautofillmlenabled]. The EdgeAutofillMlEnabled policy is the parent of this new setting, thus turning off the EdgeAutofillMlEnabled policy turns off this setting. Note: These features are a controlled feature rollout. If you don't see these features, check back as we continue our rollout.
• AI-powered History search. Enhanced search finds sites in your History even when you use a synonym, phrase, or typo. After this feature is turned on, sites you visit will be shown in enhanced history search results. An on-device model is trained using your data, which never leaves your device and is never sent to Microsoft. Admins can control availability to this feature using the EdgeHistoryAISearchEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• Microsoft 365 Copilot Chat Summarization in Microsoft Edge Context Menu. Microsoft Edge is introducing a Microsoft 365 Copilot Chat summarization menu item to our context menu. This feature helps users quickly unpack and ask questions about their open page. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Improvements to surfacing performance notifications. Microsoft Edge is making improvements to how users can learn about and improve their browser's responsiveness. Performance and Extensions Detector notifications may appear in the Settings and more menu when Edge's performance slows. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
• Copilot on the Microsoft Edge New Tab Page (NTP). Starting at the end of May 2025, users may see suggested work and productivity-related Copilot prompts by their search box on the NTP page. Also, users may see the Copilot icon in their search box allowing them to click on the icon to send their current search query to Copilot. The Copilot admin policy NewTabPageBingChatEnabled continues to be enforced and will still apply. NTP changes are rolled out to all Microsoft Edge release channels. Note: These features are a controlled feature rollout. If you don't see these features, check back as we continue our rollout.
• Adding support for viewing Sensitivity labels applied to a Microsoft Information Protection (MIP) Protected PDF. Enterprise customers can view sensitivity labels applied to MIP protected PDF to be well informed of the data classification to enable them to handle such sensitive documents. This change is available in the new Microsoft Edge built-in PDF reader. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
