Edge 147: Chromium patches and Copilot updates

# Microsoft Edge 147: Key Security Updates and AI Features

Microsoft Edge 147 released on April 10, 2026, for Windows 10/11, macOS, and Linux. This build focuses on Chromium security patches, fixes for deployment via WSUS/MSI, and improvements to autofill with malicious software blocking.

Security Patches and Stability

Version 147 includes two patches for Edge vulnerabilities and 60 fixes from Chromium. Fixed an issue that blocked deployment of Edge and WebView2 in enterprise environments when auto-update policies were disabled. This is critical for IT admins using WSUS or MSI packages.

Additionally, form autofill mechanisms and the malicious software blocker have been updated. Testing shows a 15% reduction in false positives based on Microsoft's internal metrics.

Copilot and AI Tool Integration

The Copilot chat in the sidebar has been updated: improved response speed and contextual relevance. AI settings consolidated on a single Copilot page — rollout planned for May 2026.

New Copilot New Tab page (preview): combines search, chat, and work content. Full version expected in early May. Copilot added to Immersive Reader for text summarization, explanations, and chat.

For developers: Copilot API now supports custom prompts via edge://flags/#edge-ai-custom-prompts (stabilization in 147.0.XXXX).

Enterprise Policies and Security

Intune MAM support expanded for multi-tenant scenarios: DLP control via clipboard, watermarks, and protected downloads. Microsoft Purview integrated with Outlook Web.

Improved visualization of third-party cookie settings in edge://settings/cookies. Admins get enhanced extension monitoring (preview): logs via edge://extensions-admin/.

| Feature | Description | Status |

|---------|----------|--------|

| Intune MAM | DLP for multi-tenant | Stable |

| Purview + Outlook | Expanded support | Stable |

| Cookies UI | Clearer settings | Stable |

| Extensions monitoring | Admin logs | Preview |

New Policies for Enterprise

Edge 147 enterprise builds introduce a preview version with easy rollback: policies for guest mode, InPrivate URL restrictions, download controls, PDF access, Kerberos delegation, and MAM/DLP.

Added profile shortcut switcher in Windows Taskbar. Full list of policies:

• GuestModeEnabled — disables guest mode.
• InPrivateModeURLRules — whitelist/blacklist for InPrivate.
• DownloadRestrictions — download restriction levels.
• PDFAccessControls — policies for built-in PDF viewer.
• KerberosDelegation — extended authentication.
• MAMDLPControls — Intune integration.

Deployment via GPO or Intune: edge://policy/ shows status.

Deprecated Features and Migration

Collections fully removed: no new items can be created. Recommendation — export to Favorites or OneNote via edge://collections/export.

Workspaces migrating to v2 based on Edge Sync: shared collaboration removed, sync is local. Transition automatic for existing spaces.

Custom master password deprecated: full removal June 4, 2026. Replacement — device authentication (Windows Hello, biometrics).

For migration script:

# Example migration of collections to Favorites
Get-AppxPackage *Edge* | ForEach { 
    & "$($_.InstallLocation)\edge.exe" --collections-export 
}

Key Takeaways

• 62 security patches (2 Edge + 60 Chromium) — mandatory update for production.
• Copilot in Immersive Reader and new tab — productivity boost for mid/senior devs.
• Enterprise policies for InPrivate and MAM — simplify compliance in multi-tenant setups.
• Removal of Collections/Workspaces v1 — plan migration by June 2026.
• Easy rollback for enterprise builds — minimizes downtime.
