Device Manager - Details - Display Name

This might be a minor thing or it might indicate something more sinister.

During development of the INF for a custom driver, somehow the custom class name got connected to the wrong string on my development machine. Now, no matter what I do, the device class displays “Pyrocam” rather than “NanoScan”. There is no “Pyrocam” anywhere in the INF (or in any INF for that matter - I cleared them all out just in case)

In the Details tab in Device Manager, the “Device class” displays “NanoScan”. The “Device class guid” matches the INF. The very last entry, “Display name”, displays “Pyrocam”.

I have searched the registry for “Pyrocam”. There are some entries connected to other devices. But no entry that I could find is connected to this device or this device class. I have also searched the registry for the class guid. No entry contains or is connected to the string “Pyrocam”.

Anybody know where this string is stored? Or cached?
