KB4503293 won’t install

There are some Windows 10 users who are still struggling to install this patch on their machines. The update processsuddenly stopsfor a few minutes, then resumes only to fail again a few minutes later.

The first download got to 73% downloaded and stopped. No disk, CPU or ethernet activity. I left it an hour and then it failed with no error given. It suggested restart and I did, but the restart continued and I left that an hour. Eventually I used hard shutdown and rebooted. This time it missed the download, just installed and completed successfully.
