How to Prioritize IPV4 over IPV6

At elevated command prompt run:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d 32 /f

In a Windows domain environment, you can distribute the registry entry using Group Policy Preferences. To do so, create a new GPO for the desired OU or domain, and open it in the editor.

There, navigate to Computer Configuration > Preferences > Windows Settings > Registry and select the New > Registry Item command from the context menu.

In the following dialog box, select HKEY_LOCAL_MACHINE as the hive and enter SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ as the key path. Set the name to DisabledComponents and enter 32 as the value. If you want to disable IPv6, use 255 instead.
