    Last Thuesday's Win10 Update stops MS Wireless Display from working


    I used last Saturday my MS Wireless Display Adaptor watching a movie on my TV stored on my PC.

    On Wednesday morning my PC automatically updated with KB 4343909, and since then Miracast/MS Wireless Display Adapter no longer worked, even though I have seen the following on my PC: the device is working properly, your adaptor is connected, connection failed, something went wrong, couldn't connect etc.
    I tried all internet based recommendations fixing this issue for the last two days and nothing seems to fix it.

    I went back to an Acronis Full Backup prior to the KB 43439009 update and Miracast/MS Wireless Display Adaptor works again, just like before, The problem is with the update. Am I the only one with this problem, since I found no mention of it on the Internet?

    I hope MS fix this soon ...

    What happens if you simply uninstall the update?
    You could hide (block) the update - see the relevant tutorial if unsure.
    However you will receive its content in any next update as they are cumulative.

    Having used the Acronis Full Backup and within a few minutes the update KB4343909 had been downloaded again asking me to restart the PC. I ignored this trying to decide whether I ought to disable the automatic WIN10 backups.
    I tested the Miracast/MS Wireless Display Adapter and it worked perfectly - just like before.
    Then I did a few other things and after a couple of hours or so I found that the KB4343909 was now installed.

    This time I was able to connect my PC to the TV without any problems!
    And it is still working now ...
