Yeah. Tried that too.
Btw. when I have closed down wscript.exe and shut down OVRservice_x64.exe, the OculusConfigUtil.exe is showing my DK2 as "disconnected." And anything I do in the OculusConfigUtil is very slow. F.ex. going to Advanced, and down the submenus takes longer than usual.
Had that issue, and used the Oculus runtime utility (link in the op). Basically, you also need to kill the config utility before you will get a response on the secondary screen.
