We use this sparingly at work as this have a bad rap and yes sometimes something goes very very wrong during the uninstalling. I have managed to manually remove everything related to these adapters but it's not a fun process. You will to manually delete any drivers, the built in pnputil.exe program will work fine. You need to manually remove the service and registry keys that go with this it under HKLM\SYSTEM\CurrentControlSet\Services\<Service Key> and you will want to remove the service out of ControlSet### these are your system restore(s). You will also need to find and delete and CLSIDs assoicated with the driver and software, also delete all the entries under HKLM\Software as well as clear out all the files.
