stop ipv6 from automatically enabling

How to stop ivp6 from automatically enabling ? I tried to disable it in registry and it didn't work and i can't disable it in my modem. I don't know any other way, i want to stick to ipv4 for now. How to prevert ipv6 from automatically enabling ???

It seems it is causing my vpn, when i connect to a server. I contacted them..

Still not sure why when i connect to a vpn and than disconnect ipv6 enables for all adapters.
Hm they offered only this: https://support.microsoft.com/en-us/...advanced-users
Using microsoft fixer, or disable via registry - both doesn't work.
I currently don't have ipv6, but i can get it at any point and i don't wanna mix my traffic from virtual machine and windows. Also still sending some packets, guess it will be some basic networking like dhcp or something.
Is there any other way to uninstall ipv6 or disable it ?

Did you try what I posted back in post #2? Disabling it in your adapter? I don't see any mention that you did.

Yep, also i tried TairikuOkami's script. I tried everything i found.

FreeBooter - scrip says:The term ':_Ex' is not recognized as the name of a cmdlet, function

Also problem is not to disable it, because every time after i connect to vpn and after disconnecting ipv6 reenables on all adapters. And i tried every solution they told me, which is in that link above and they said they can't offer anything more.
I need uninstall ipv6 which is greyed out. Or remove some windows files so it doesn't work at all!!
Don't know why it is reenabling each time bizzare bug indeed...
