For many people using VMware Workstation they should be aware of an issue which occurs after updating Windows 10 to the new Windows 10 Anniversary. In fact I have run across this issue with other major Windows 10 updates.
After performing a major update to Windows 10 VMware Workstation’s VMnet0 is removed. The removal of VMnet0 breaks the network connection for guest Virtual Machines. To repair connectivity for the guest Virtual Machines you can add a new virtual network or set the Virtual Network back to their default settings. If you set the VMware Workstation network back to default settings you will lose any and all custom networks.
