Just an update !
I had to reboot my computer after uninstalling McAfee with your link but the computer was installing updates whilst I did it. I rebooted and went into updates installed and it didn't show the two files it had updated yesterday and none for today, but found them in "View the update history" when I selected the option "hide/unhide" updates where it showed in the "status" column that they had succeeded. So don't understand why these two updates are not showing in the "Installed updates" file.
Also the "Windows Update" facility, when started afresh, appears to be "hanging again" in "Downloading updates" as it states beneath "Downloading 93 updates, 0kb Total, 0 complete", which seems strange to me as I always thought this showed the progress of downloads as they come through.
Am I going mad, or has the update facility changed in how it works ?
