I highly recommend not fooling with these folders, you can do more damage than harm. If Driver Store Explorer doesn't list it, the damage is already done.

Why do you care so much anyway? A driver file that has no service loaded simply just sits there as any other file, it does nothing but occupy a few kilobytes of disk space so I don't understand what we're discussing here...

Heck, every Nvidia GPU driver update leaves countless outdated files on the system, who cares 😁
