Need to completely remove a device driver in windows 7

Question

I have an old USB device that is not recognized by windows 7, so I grabbed the device driver for the chip that handles the USB communications. After I modified it I used it to install for the device. Stupid I know, but now I need to get rid of it.

Below is the code from the inf setup file. This does not have the VID and PID that I changed. I need to reverse all the changes it made.

Another option (the Microsoft way, without doing random unknown deletings in the registry) is to start CMD as "run as admin" and then list all installed drivers in the Windows 7 driver store via:

pnputil -e

if this caused a longer list you can pipe that into a file via:

pnputil -e > C:\driverexport.txt

If you have found now the driver you need to remove use the following comand:

pnputil.exe -d OemNUMBER.inf

replace NUMBER with your number from your example. You might try to use -F to force the uninstallation. Once a reboot is done the driver should be gone.

This might be also usefull to delete old drivers and get some HD space back.
