Is this a possible scenario? I understand when it comes to DriverStore (previous approach), which can contain multiple drivers, but we've switched to an approach where the driver currently in use is requested. Is it possible that multiple drivers are in use at the same time?

Yes, after updating the driver, but before reboot, It lists 2 versions of igc64 loaded for dwm.exe. I suppose this it is done on purpose to allow fast fallback on driver crashes.

For example, see #5440 (comment).

However your comment highlighted another issue: when an interactive session is present on machine, this will return "MULTIPLE" despite there's only one library, since we have 2 dwms in this case: one for a login screen, and one for a session. I'll fix it with something like sort -u

What do you plan to do if script return MULTIPLE? Will this be a signal that the machine needs to be rebooted?
