Windows 10: No URL protocols work (http, steam, ms-settings, ...) - "OS can't run" Solved

    No URL protocols work (http, steam, ms-settings, ...) - "OS can't run"

    EDIT: Solved! The second error message I found (about missing ordinal #581 in ieframe.dll) was the clue I needed. The problem happened because I had IE Dev Preview installed. It's an App-V package and it can be easily uninstalled by running these commands in PowerShell (Admin):

    Set-ExecutionPolicy RemoteSigned
    Import-Module AppvClient
    Get-AppvClientPackage -name "Internet Explorer Developer Channel" | Remove-AppvClientPackage


    after my upgrade to Windows 10 all URL protocol associations stopped working.

    Whenever a protocol link is supposed to be opened, either nothing happens or I get a message like this:

    [Window Title]
    Das Betriebssystem kann nicht ausführen.
    ...which basically says "The OS can't run"

    Examples of the effects of this:
    - Clicking the "Notification settings" button inside the start menu properties doesn't work and will show the error about "ms-settings:notifications".
    - Clicking on a web link inside my email program does nothing.
    - Trying to open a web page from the "Run" dialog shows the error copied above.
    - It's not possible to run any Steam games from start menu (since they use a link like steam://rungameid/12345).

    The associations are shown correctly in the control panel, and in the registry, they also look OK.

    What could be wrong?

    Best regards,

    I just noticed something else: Trying to open certain links in applications (such as the "Open Xbox" link inside the game bar Win+G) will cause this error:

    GamePanel.exe - Ordnungszahl nicht gefunden
    Die Ordnungszahl 581 wurde in der DLL "C:\ProgramData\App-V\9BD02EED-6C11-4FF0-8A3E-0B4733EE86A1\6A0357B5-AB99-4856-8A59-CF2C38579E78\Root\VFS\System\ieframe.dll" nicht gefunden. 
    (saying that the export with ordinal #581 wasn't found in ieframe.dll)
