Driver deployment error - "Cannot create a stable subkey under a volatile parent key."

[John Dr]

I've just started to create a new UWP driver using WDF "UMDF v2" I've provisioned my target device (Windows 10 14393.969) with the installer in the WDK directory (C:\Program Files (x86)\Windows Kits\10\Remote\x64\WDK Test Target Setup x64-x64_en-us.msi)


After provisioning the device with Visual studio->Driver->Test->Configure devices, I try and debug the driver I get this:

Looking in the mentioned log files, I can see

I'm starting to dig through the documentation to see if there's anything else that I've missed, but was expecting it to have worked.

Any ideas?


Thanks in advance
