Windows 10: Diagnostics Policy Service stuck while stopping

Diagnostic Policy Service - high CPU

HP laptop problem
In the last few days, this laptop started having poor performance, with Task manager showing Diagnostic Policy Service taking up to 30% or more of CPU.

HP Spectre x360 - 13-4197dx (ENERGY STAR)

Did upgrade of BIOS, no improvement.
Downloaded all current windows upgrades – no fix.
I created a new (admin) user, same problem.
I ran all of the diagnostics in the HP Support Assistant, all passed – no effect.
I ran "sfc /scannow." and "Dism /Online /Cleanup-Image /RestoreHealth" – no effect.

There is an online thread on this in the HP forums, which does not seem to show any fix.

The HP support is abysmal – it took several minutes for him to echo back “so this is your computer system?”, and then the only suggestion was a factory reset.
