Another simple one that disables IPV6 from powershell for Server and Hyper-V 2012.
New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters -Name DisabledComponents -PropertyType DWord -Value 0xffffffff
So that’s one command and you can simply copy and paste into power shell. You will need to have admin privs for this to work.

You are not supposed to disable IPV6 in Hyper-V. Do not do this.
Can you point to the documentation that says you shouldn’t?
