Hello, just a status update on this, and sorry for the delay. Many sorts of "playing around", i.e. renaming the tun interface seem to fix the problem permanently. E.g. renaming the adapter forth and back will leave you with a permanently working system. So I now believe this is not only about the adapter names but rather about some subtle change in some other part of the environment, perhaps not even the registry. So to reproduce the error, you need a fresh install almost every time you try something. This is no big deal with a VM image, of course, but cornering the error might require more than dumping a registry branch "before" and "after". I hope that in a couple of weeks from now I am able to report something more detailed as I should have a little more time then. It is a minor issue anyway, and most users of German Windows running into this probably have hit the point where the problem was simply gone. But: The windows port itself _is_ important. I have a production case with a set of clients that need to set up all routing by themselves -- which is something you can't do any more with Anyconnect.
