My 168B+ is working, not flawlessly, but it's working with Win 10 1607. Sometimes the display goes blank and I have to re-plug all my USB monitors.
What bothers me most is that
I'm unable to adjust brightness and screen rotation any more.
I got no response from DisplayLink and there was no sensible answer from Asus support. It's obviously a driver issue, because on my old machine (still running Win 10 1511) all buttons are working as expected.
