I have the Nvidia GeForce GT 640 Video Card and I received an update
notice for the device in Win7. I see people have problems with some
card updates and am wondering if I need/should update Win7 with this
one, and what happens if I do not. The update is "NVIDIA Corporation
- Audio Device, Other hardware - NVIDIA High Definition Audio Download
size: 3.9 MB". Anyone has applied this update and care to share
experience?

This is on a Dell Desktop computer.

Thanks for any insights.

That sounds like audio-over-HDMI.

Does your computer monitor have speakers ? Are you connected
over HDMI ?

The capability might not be of much use to you, if you're not
connected that way. My audio goes to my analog computer speakers,
so that Nvidia update wouldn't do anything for me.

As a general recommendation, don't take hardware drivers from
Windows Update.

If you're having an actual problem with your Nvidia product,
you can go straight to the Nvidia.com web site, and try another
driver from there.

A typical reason for updating a video driver, might be to improve
game compatibility, get better frame rate performance.

You can roll back a driver, from Device Manager (one level of rollback
is supported, not an infinite number of levels). I prefer to just
keep copies of all the ones I've used, and uninstall the old one,
then install whatever version I want to try. When you uninstall
the video driver, the default system VESA driver is used in its place
(so you can continue to see the screen). So even when you don't
have a video driver installed, there is actually a video driver
being used, a fallback driver. The fallback driver is written
by Microsoft.
