GPO Force InPrivate browsing setting breaks webview2 client.

artroy ,

A few questions/suggestions:

• You mentioned "multi app use": Is this referring to the multi-app kiosk mode in Windows? If not, have you tried evaluating this mode for your needs? Set up a multi-app kiosk on Windows 10 - Configure Windows | Microsoft Docs
  • This mode locks Windows down to only the allowed apps and prevents the regular taskbar and "normal" start menu from showing up.
  • Here's an example solution post that maybe of relevance to your needs: Setup an Edge Chromium based Kiosk device with Microsoft Intune | (inthecloud247.com)
• You mentioned trying out Edge kiosk as an attempt to migrate from WebView2, though, "After making that change all webview2 clients threw an error upon launch" indicates the apps are still using WebView2. Is this still a requirement?
• Instead of forcing InPrivate mode, have you tried other policies to prevent users from modifying settings? Here are some suggestions:
  • AddressBarEditingEnabled - though this would mean users CANNOT modify the address bar contents at all
  • URLBlocklist and/or URLAllowlist

Let us know how this goes 🙂
