I am almost ceratin that I never explicityly loaded these drivers so I
think they are available from within either Windows 8 or 10; the PC came
with Windows 8 originally. In any case the Prolific drivers can be found
online. I have just checked and it is working fine.
========================================

Sure, it's always worth trying it before concluding that something new is
needed - Win8/10 etc are getting much better at finding drivers
automatically than ever used to be the case with older versions of Windows.

But Prolific in particular went through a phase where they were very slow to
write new drivers especially for their older USB chipsets. To the best of my
knowledge, some of the older ones have still never been updated for Win8/10
compatibility - maybe there's some technical issue as to why it can't be
done.

Looking at the Prolific website it does state:
NOTE:

Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL chip versions.
Run PL2303 CheckChipVersion tool program in Windows XP/Vista/7 to check chip version.
Windows XP, 2000, 98 and Windows ME driver technical support is discontinued.
Prolific recommends to use PL-2303HXD (HX Rev D) or PL2303TA chip.
