Delete device and driver

In order to delete a device from the device manager we can use pnputil /remove-device command but we must know the instance id to delete the correct device

to filter for example realtek devices go to the device manager and select the properties of the appropriate device and in the details tab select the property class GUID

ex: pnputil /enum-devices /class {4d36e96c-e325-11ce-bfc1-08002be10318}

this will show the results of all the audio devices

ID d'instance :                 HDAUDIO\FUNC_01&VEN_10EC&DEV_0280&SUBSYS_102805A4&REV_1000\4&23955602&0&0001

To select the correct instance id find the realtek audio device with the status debut/started. You can also crosscheck the same from hardware id properties in the device manager details tab under hardware id

so in my case:

pnputil /remove-device "HDAUDIO\FUNC_01&VEN_10EC&DEV_0256&SUBSYS_10280AC7&REV_1000\4&3110e0b5&0&0001"
pnputil /delete-driver oem299.inf /force
pnputil /delete-driver oem5.inf /force
pnputil /delete-driver oem80.inf /force
pnputil /delete-driver oem177.inf /force
pnputil /delete-driver oem339.inf /force
pnputil /delete-driver oem338.inf /force
pnputil /delete-driver oem192.inf /force
pnputil /delete-driver oem125.inf /force

Note: first delete the device and then delete the drivers.
