In trying to switch to the IM driver to see if it yields the same issues, I’m not able to successfully install it. I’m getting error code 0x80070436 when running snetcfg, indicating “The name is already in use as either a service name or a service display name.” I’ve uninstalled the LWF drivers with snetcfg, and used pnputil to clear out all the LWF instances in the driver store. It seems to still have a reference to the LWF driver and won’t let me install the IM driver since it has the same name.
Try to remove cached INF/PNF files from WIndowsINF folder.
