Install a 64-bit Microsoft PDF Preview plug-in from the Microsoft Store, or set the Preview pane as the default program in Settings, and you'll be able to fix it.

    Since this month's updates, I'm unable to preview PDF's in Preview pane, since all the files that are marked as MTW ("Mark of the Web") are considered to raise security issues. My problem here is that it is preventing from Preview even files that are stored locally at the desktop or the documents folder ( and they are not blocked due to this MTW attribute ).

    My workaround was to add them as trusted sites in the Internet Options but this is just a workaround and there may be other folders in this situation. Is there anything else I can do besides uninstalling the updates or applying this workaround?

    Thanks.
