, I have today managed to clear most of the backlog of updates that were queued up, having failed to complete update. Most of them were HP and Intel driver updates, but a couple were MS updates.
By a process of trial-and-error, I got them all to go though successfully, bar one: Hewlett-Packard Development Company, L.P. - Keyboard - Standard 101/102-Key or Microsoft Natural PS/2 Keyboard for HP Hotkey Support
(released in April 2014). It just will not
complete an update.
The current driver is of 2006 vintage!
