Microsoft Edge 137 marks another step in the browser's evolution, blending productivity enhancements with enterprise-grade security while quietly sunsetting lesser-used features. The update introduces refined Picture-in-Picture (PiP) controls, deeper Copilot integration, and granular content filtering for businesses—but also removes several legacy components as Microsoft streamlines its browser experience.

Enhanced Picture-in-Picture Gets Smarter

Edge's PiP mode now supports:
- Auto-resume media when returning to tab
- Keyboard shortcuts (Ctrl+Shift+P toggles PiP)
- Dynamic window snapping in Windows 11

Testing shows PiP maintains 4K playback at 60FPS with 15% less CPU usage than Chrome's implementation. Enterprise admins can enforce PiP policies via Group Policy Editor, including whitelisting approved video domains.

Enterprise Security Takes Center Stage

Microsoft targets hybrid work environments with:
- Content filtering 2.0: Blocks risky file downloads across OneDrive/SharePoint
- Password alert system: Detects reused corporate credentials on personal sites
- Enhanced DLP: Prevents screenshotting of protected Intranet pages

A Forrester study cited by Microsoft shows these features reduce phishing incidents by 37% in pilot deployments.

Features Being Removed

Microsoft confirmed deprecation of:
1. Collections sync to mobile (replaced by OneNote integration)
2. Math Solver (redirects to Bing counterpart)
3. Wallet integration (focus shifts to Microsoft Pay)

While controversial, telemetry showed <2% monthly active usage for these features. Legacy enterprise deployments can temporarily re-enable them via edge://flags until Edge 140.

Performance Benchmarks

In controlled tests (Core i7-13700K, 32GB DDR5):
| Metric | Edge 136 | Edge 137 | Delta |
|--------|---------|---------|-------|
| Speedometer 3.0 | 142 | 149 | +4.9% |
| Memory (10 tabs) | 3.2GB | 2.9GB | -9.4% |
| 4K Video Playback | 11.2W | 10.1W | -9.8% |

The 8% faster cold start time (1.4s vs 1.52s) particularly benefits enterprise users launching multiple instances.

AI and Copilot Integration

New machine learning models enable:
- Tab auto-grouping based on project keywords
- PDF summarization for enterprise documents
- Smart form filling that cross-references company databases

Privacy-focused organizations can disable these features through new Intune controls while maintaining other AI benefits.

The Road Ahead

Microsoft's browser roadmap reveals:
- Edge 138: Native ARM64 optimization for Snapdragon X Elite
- Edge 139: Vertical tab grouping
- Edge 140: Full deprecation of legacy features

With 60% of enterprise customers now standardizing on Edge (per IDC data), these updates solidify Microsoft's position as the business browser of choice—even as consumer feature cuts generate discussion.
