Do I understand you correctly, if you do a fresh install of RC1, this does not happen, but with RC2 it does?
There have been a few changes in the tap and msm and openvpnmsica side of things, but I had assumed that nothing would affect "what windows thinks the resulting adapter is like" (and, if I read the commit log right, only the "MAC address" stuff is in RC1 -> RC2).
@selvanair: could this be related to the (new) absence of "MAC"?

I think this must have started when we tagged the adapter as virtual (not ethernet) around release 2.4.8. It used to show up as an "Ethernet adapter" before then. The device manager will list it a "Tap-Windows Adapter v9" device.
@cron2 - I rolled back to OpenVPN-2.5-beta3-I602-x86.msi
, the status was also unknown

So, what Selva said - we changed the adapter type from "Ethernet" to "virtual" quite a while back (2.4.8).
I can't seem to find the relevant PR, but here's the commit

2.4.8 may have been neglected ...
I just built 2.6_git
for Windows and this is still the same; Unknown adapter Local Area Connection 2:
for TAP
and wintun
.
@TinCanTech is this issue still relevant or has it been fixed in the mean time?

Note: DCO in topology NET30 ..
As discussed earlier, this appears to have started since we changed IfType in the tap driver from ETHERNET to IF_TYPE_PROP_VIRTUAL (== Proprietary Virtual/Internal). In retrospect, not surprising as it used to show up as an Ethernet adapter but is now "Proprietary" which is arguably same as "Unknown".
We have not touched it since, so no change is expected in 2.6.
I would say just read "Unknown" to mean "Proprietary", and let it be. The description says what it is.
<offtopic>
@selvanair did you have a chance to try dco-win driver? have you noticed any difference? </offtopic>
difference in performance? As dco is the default now, my connection(s) have been using it, but my usage of VPN on Windows is only for some routine remote access, nothing performance critical. I heard some good feedback from others though.
As for this "Unknown adapter" thingie, dco-win could probably set the IfType as IF_TYPE_TUNNEL (131) instead of IF_TYPE_PROP_VIRTUAL (53)?
Using 2.5-rc2-I601-2-x86.msi, the install all works for me (I know there are some things going on under the hood but I have not investigated those).
But just for the record, the network adapters are "unknown".
