  1. Short instructions for those who could not find any registry entries (like me) and the problem persisted:

    Navigate to > C:\Program Files (x86)\Microsoft > DELETE > Edge folder
    Download dir > https://easyupload.io/vrvea4 > (Ver. 104.0.1293.70 FIX) > Password to download: 123451 > Navigate again to > C:\Program Files (x86)\Microsoft > paste the “Edge” folder and open Edge. After that, the Edge Browser in Ver. 104.0.1293.70, then (if you want the latest version) close the Edge browser via Task Manager and navigate directly to the Windows search bar and type > Apps > navigate to Apps & programs > search for Edge > Change > Repair. Once the Edge browser has been reinstalled, open Edge again and the latest version 112.0.1722.58 (Official Build) (64-bit/32-bit) should be installed and updated. After that you can via. Check the settings in the Edge browser again for updates and you’re done.

    Best regards from,


    PS Did that and haven’t had any problems since.
