How to diasable IPv6 from windows

Microsoft windows provides a native support for IPv6 protocol. And it is loaded  in memory by default. This is an advance protocol which will replace the IPv4 which is the present standard protocol. But unless your network does not require IPv6 you can securely disable it to free up system memory.

First, click on the Start Button and type in regedit and hit Enter.
Then, navigate through HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, services, TCPIP6 and Parameters. Right click on Parameters and select New and then DWORD (32-bit) Value. Name the new value DisabledComponents and hit Enter. Now right click on the new DisabledComponents value you just created and select Modify. Set the value of DisabledComponents to FF and click OK.

Then reboot your system and IPv6 will be disabled from all interfaces.
