Windows update 17115.1 GSOD during "working on updates"
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.
