I had that same problem as you - even after I disabled auto install in windows settings.
But here's what worked for me and you can try it. Copy paste job:
- Go to Start–>Search type in gpedit.msc
- Click the file to open the Local Group Policy Editor
- You want to go here: Computer Configuration->Administrative Templates->System->Device Installation. Click on the subfolder Device Installation Restrictions on the left and on the right side you will see the possible restrictions.
- Right Click on Prevent Installation of Devices not described by other policy settings and edit this option, set it on ENABLED.
- Reboot Windows and enjoy its inability to pollute your system with its standard driver, open gpedit.msc again and revert the change so you will be able to install your driver.
After the reboot , don't forget to revert the change using gpedit.msc before installing your driver.
