I tried the first one just searching for the words Diagnostic Policy Service. Nothing happened at all apart from telling me there were no connection. I tried a few times. I assume your method is just do Windowskey+Q and search for anything and the search action helps. But it did not unfortunately.
Your other method I tried and did not get response there either, - but only once. I will try that one again a few times.
We all want it to work, but it is frustrating it does not work. If a person with the knowledge looked at it then there would be a solution in an hour.
Then I have tested the other method. No success - it did not connect to anything and came with error message Code 80072EFD and the connection still stayed deconnected.
