I have a problem in my network and sharing center. I allowed windows updates and got an update. Then I faced the problem. My VirtualBox Host-Only Adapter looks like "Ethernet 3" on my network and sharing center. When I try to change its IPv4 address to 172.16.3.1, it gives the warning "This IP address is already assigned to the VirtualBox Host Only Ethernet Adapter adapter on the computer." I reinstalled VirtualBox to fix the problem, but there is no change. It still gives the same warning.
