Windows update insisted I needed to update my NVIDIA video drivers.
False (and you know it). Windows Update never forces you to get
hardware updates. YOU chose to install the hardware (driver) update and
that's what you did: you saw it offered and couldn't resist installing
it. So what was not working with your current setup that you thought a
new driver would fix? Microsoft provides no details aka release notes
on what a new driver version will fix. For that, you have to visit the
hardware maker's web site, see if THEY offer an updated driver, and
check what it fixes (if they tell you; else, check the forums or contact
them for details).
Or do you really mean that you configured the WU client to perform
automatic downloads and apply updates without your intervention because
you chose to let Microsoft change the state of your computer whenever
they feel like it? No one should leave the WU client configured for
automatic updating. Either set to Never (and choose when you want to
check for updates but after saving an image backup) or have it prompt
you about available update but YOU choose which ones to install.
Note: Despite how the WU client is configured, Microsoft has been found
to push updates, especially those for updating the WU client itself.
Users that have the WU client set to Never or prompt have sometimes
found themselves waiting during a shutdown for an update to apply for
which they were never notified or which not allowed by the user, and
more updating on the next startup of Windows. The only sure way to
thwart Microsoft from changing the state of your computer is to disable
both the Windows Update service and the Background Intelligent Transfer
Service (BITS) service. Disable them and then reenable them later when
you decide it's time to check and choose which updates to get.

Now there is NO sound !
So try a System Restore after the *un*forced driver update. System
Restore doesn't always work (for me, it's a coin toss). That's why you
should be doing regularly scheduled backups and also perform a backup
before committing major surgery to your computer's state.
Never get driver updates via Windows Update. Only use the notification
of a new driver to go to the manufacturer's own web site to see if THEY
offer a driver update applicable to the hardware you actually have.
Drivers at Windows Update are often "family" drivers, so WU might
incorrectly detect your hardware as within that family or use the driver
for a different model in that family than what you have.

I fiddled for a day or two and gave up and fortunately could undo the
Sound is now back ! But the video driver update is undone.
So right-click on it in the WU list and choose to Hide it -- if seeing
it perturbs you so much that it become irrestible to you. You can
ignore any update offered by the WU client in Windows 7 (a level of
granularity in control not afforded in Windows 10). You could elect to
hide it in the list (until a new version of the same update appears
later - hiding is by version of an update, not for all versions of an
