Don't know from where you are getting drivers with that software. Also,
not having the latest driver is not some serious flaw in configuration.
Sometimes older drivers work better than new one. New code = new bugs.

Did you configure Win10 to *not* update the hardware drivers? You could
roll back to the prior driver version.

Uniied corded. If I have identified the model correctly Corsair has a
K520R and Dell has just been fitted with a MK270R.

Those are wireless mice, not corded.

I thought that was a problem with the Dell when I found the battery in
the mouse had ruptured and oozed inside he mouse.

Every battery I've had leak was made by Duracell. Despite all their
advertising, I've found them to be the most destructive (other than
those really crappy cheapies that come with the hardware).

Do you think people really can tell exactly what role the various
startup programs/services play in the swamp that is Windows 10?

Yep, they can. Looking at the path for the executable can indicate what
it is for. Right-clicking on the file and looking at Properties -
Details can sometimes reveal who made the software and what it is for.
Sometimes you have to search the web.
