Perhaps it'll seem trivial but I don't realize how to have this feature
working.
I never found that a driver was backed up so that I could see driver
rollback effectively rolling anything back.

I'd like to learn about this issue: does one need to enable something
special, or explicitely choose to save the older copy of drivers?
I know about uninstalling enite applications, or system restore points only
to overcome driver problems...

thx in advance,

You don't have to do anything. When drivers are installed the .inf, .pnf, .sys and (if applicable) .cat are placed in a drive on the system. When you update drivers, those files are place on the drive as well without touching the previous driver files. As long as you don't delete the files or they don't get corrupted, clicking the "Roll back driver" button will uninstall the presently installed driver and reinstall the driver just previous to it.

You can find the files mentioned above in both:
c:\windows\.inf
and
c:\windows\system32\drivers
