What is msedgewebview2-office.exe?
msedgewebview2-office.exe is the Microsoft Edge WebView2 runtime component embedded in Microsoft Office applications to render modern web content (add-ins, task panes, and online features) inside Word, Excel, PowerPoint, and Outlook. It enables web UI without launching a separate browser instance.
This process hosts embedded web content via the Chromium-based WebView2 runtime, sandboxed within each Office app to provide secure rendering and isolation for web-driven features.
Quick Fact: WebView2 lets Office render web-based UI using the Edge browser engine, ensuring consistent rendering across Office apps.
Types of WebView2 Processes in Office
- Office Main: Main Office app window and UI (one per app)
- Renderer/Web Content: Each web-based task pane or add-in (multiple)
- Background WebView: Background web views for syncing or previews
- Plugin/Component: Plugins or internal components that host web content
- Utility/Helper: Background helpers related to web content rendering
- GPU/Rendering: Renders hardware-accelerated UI for web content
