Edge is broken after safe mode

Today I wanted to test if remote desktop programs can launch in safe mode. Here is what I did.

  1. Enter safe mode with network.
  2. Try to launch rd programs and fail.
  3. Open Edge to check if network is working.
  4. Restart.

Then weird things happened:

  1. Edge profile is logged out.
  2. All web sites are logged out.
  3. All search engines in settings lost.
  4. Extension "iTab New Tab" is disabled.
  5. There is a message "managed by your organization" at the bottom left on extension page.
  6. Some of my extensions have a yellow icon at bottom right which says "unpacked extension" which is incorrect because they are installed from microsoft extension site.
  7. Every time edge launches there is a "extension run in developer mode" message while the developer mode switch is off.

I tried resync profile, remove readonly attribute of "%LOCALAPPDATA%\Microsoft\Edge\User Data\Default"(which has a size of 1.61GB) and restart but none of these works. Passwords and other settings remain unchanged (At least the ones I checked).

What I worry about is that my system may has been modified in other places other than Edge.

    Edge itself is likely corrupted, not the whole system. Safe Mode can interfere with user profiles and extensions, and a damaged Edge profile or install can cause exactly the symptoms described (sign-out, extensions treated as “unpacked,” “managed by your organization” banner).

    Use the following sequence to repair Edge and the profile.

    1. End all Edge processes
    • Press Ctrl+Shift+Esc to open Task Manager.
    • End every msedge.exe process.
    • Close Task Manager.
    1. Start Edge with a temporary test profile
    • Open Command Prompt.
    • Run: 
        "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --user-data-dir="%TEMP%\edge-test-profile"
    • Check whether:
      • The “managed by your organization” message disappears.
      • Extensions behave normally.

    If the test profile is clean, the original profile is corrupted.

    1. Create a fresh Edge profile
    • Close all Edge windows.
    • Go to %LOCALAPPDATA%\Microsoft\Edge\User Data.
    • Rename the Default folder to Default.old.
    • Start Edge normally; a new Default profile folder is created.
    • Sign back into the Edge profile and let sync restore data.
    • If Edge is stable, optionally copy specific data (for example, Bookmarks) from Default.old into the new Default folder.
    1. Repair the Edge installation If problems persist even with a new profile:
    • Make sure Edge is closed for all users.
    • Go to Start > Settings > Apps > Installed apps.
    • Select Microsoft Edge > Modify > Repair.
    • Confirm the UAC prompt and stay connected to the internet while repair runs. Browser data and settings should not be affected.
    1. General system checks (optional) If Edge still behaves abnormally after the above:
    • Restart the computer once more.
    • Ensure Windows Security or other security software is up to date and run a malware scan.

    If the temporary profile and new profile both work normally, the issue is confined to the old Edge profile and does not indicate broader system modification.
