How do I turn off the warning when opening a file from an unknown publisher?

Whenever I click on a video file, I keep getting a prompt that says, "Open File - Security Warning." (This didn't happen in the past.) It then asks, "Do you want to open this file?" It's listed as an "unknown publisher," generally if someone e-mails me a video. I can uncheck a box that says, "Always ask before opening this file," but it only helps with that ONE file. This is annoying when I'm working with many different video files.

I've looked for other answers and just found suggestions for configuring "Local Computer Policy," which doesn't even seem to be on my Windows 10 laptop.

How can I turn off the prompt for certain file TYPES without telling my computer to run any program willy-nilly?

    Try unblocking the files that you downloaded.

    If that works you can set up a shortcut on your desktop that you can run after you download files.

    Hi there,

    If you are an Windows home user you might not get the option to edit the GPO.

    In your case you can try to edit the registry and sort this out. Be carefully while editing the registry and it is advised to back up the registry before this.In the Registry Editor (regedit) navigate to

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Associations

    -In the right pane of Associations, double click on LowRiskFileTypes.
    -Add or remove file the extensions using the same format, and click on OK when finished.
    -Close regedit, and reboot your computer.

    The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue. https:// social.technet.microsoft.com/Forums/windows/en-US/5277371b-dea2-4a2b-802a-bbdc639f627f/disable-open-file-security-warning-unknown-publisher?forum=w7itprogeneral

    An unknown publisher warning while running a file or software occurs when the system does not recognize the identity or source of such file, and hence the system considers it a threat to open or run such file and warns the user through a warning popup message when a user tries to open or run on their system.

    Check out a simple guide about Unknown Publisher Warning and Useful Tips on how to get rod of such warnings allowing you to run the file smoothly on your system. More at https://signmycode.com/resources/unknown-publisher-warning-what-is-it-why-should-you-care
