a couple of days ago I deleted MS Edge.
Edge is treated as a core system component. Never uninstall Edge from windows OS.
Here's a list of side effects of uninstalling edge from Windows 11 given by Copilot..
Uninstalling Microsoft Edge from Windows 11 can break certain system features because Edge is tightly integrated into the OS. Most users who remove it experience issues with system components that rely on Edge’s rendering engine, and Microsoft does not officially support full removal.
What Actually Happens If You Remove Edge
Microsoft Edge provides the underlying WebView2 engine used by many Windows 11 components. Removing Edge can cause:
- Widgets panel malfunction
- Settings pages failing to load
- Help & Support pages breaking
- Some apps that rely on WebView2 to crash or display blank contentGeekChamp
Even if you remove it using command-line methods, Windows Update may reinstall Edge during:
- Feature updates
- Cumulative updates
- Security patchesThe Droid Guy
Windows 11 uses Edge for:
- Opening certain system URLs
- Microsoft account login flows
- Some internal documentation pages
Removing Edge can cause these links to fail or open incorrectly.
- Unexpected crashes
- Reduced system stability
- Errors when launching apps that expect Edge to exist
If your goal is simply to avoid using Edge, these options are safer:
Change your default browser
You can set Chrome, Firefox, Brave, etc., as the default for all protocols.
Disable Edge from auto-launching
You can prevent it from opening automatically without uninstalling it.
