Mgr. with !) with the only clue being ""Device Instance Id"" of ""ROOT\NET\0002"" (all other properties were blank). I have attached ""ROOT%NET%0002 - added by repairing VBox.zip"" which has good WinReg entries referencing the same adapter AFTER I had identified it as VBoxNetAdp.sys. The good WinReg entries and the bogus WinReg entries are now BOTH in the WinReg. How did I do this? I tried to update the Unknown Adapter driver. I found that the only thing that Windows would accept was Oracle Corp., Host-only. When I updated the Unknown Adapter driver to the Host-only driver, the Unknown Adapter DISAPPEARED (leaving only my original Host-only Adapter). Curiously, my original Host-only connection now has this as it's IP: 169.254.27.11/16. The original (before the Unknown Adapter disappeared) was 192.168.56.1/24. How did the bugus WinReg entries get made? I had reinstalled (""Repair"") VBox three times. There were 3 bogus entries. Coincidence? It seems to me that VBox is not cleaning up the WinReg. Your mileage may vary. This problem prevented me from getting host-only working. I would appreciate a prompt reply regarding whether you'd like me to make any tests or send any additional." defect closed installer VirtualBox 4.1.18 obsolete Windows Windows
