If no bridged adapters show up in the Networking section of the VM settings, this typically means that the bridged networking driver was not installed properly on your host. This could be due to the following reasons:

• The maximum allowed filter count was reached on the host. In this case, the MSI log would mention the 0x8004a029 error code returned on NetFlt network component install, as follows:

  VBoxNetCfgWinInstallComponent: Install failed, hr (0x8004a029)

  You can try to increase the maximum filter count in the Windows registry using the following key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters

  The maximum number allowed is 14. After a reboot, try to reinstall .

• The INF cache is corrupt. In this case, the install log at %windir%\inf\setupapi.dev.log would typically mention the failure to find a suitable driver package for either the sun_VBoxNetFlt or sun_VBoxNetFltmp components. The solution then is to uninstall , remove the INF cache (%windir%\inf\INFCACHE.1), reboot and try to reinstall .
