    Lost com ports after KB4550945 installed


    I have Win 10 v 1909. When the update was installed, I lost access to a number not all of my com ports.

    I tried to remove the update but it did not change the situation. I tried unplugging and then plugging the USB devices; again no help.

    Is this a bug in the update? Is there a fix?

    Just install PlayOnLinux? Why did they make step 2 and 3 of this "tutorial"?

    Anyway, looking at the supported software list for PlayOnLinux, D3 is a step in the right direction. Lack of gaming is a factor for a lot of people when deciding on an OS, if more recent games get ported it may help migrate them to their preferred choice.
