Always gets to 42%.

IRQL_NOT_LESS_OR_EQUAL

or

DPC_WATCHDOG_VIOLATION

Error is in CLASSPNP.SYS

It appears to be a problem with bad drivers, but which driver(s) and how to fix?

A quick update - problem now resolved and Windows updated successfully.

HP Support were able to sort the problems out, which mainly seemed to be by reinstalling their Support Assistant app.
