How to permenantly disable delivery optimization?

Question

Currently I am struggling with delivery optimisation using up my bandwith. As well as Background intelegence trasfer service. To prevent delivery optimisation from running I have been doing this....

1. Open Registry Editor.
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DoSvc.
3. In the right pane, double click on Start registry DWORD.
4. Set it to 4 and click OK.
5. Restart your system. the problem is after a while the registory resets and delivery optimisation starts back up again, are there any permenant solutions? I have found a method that prevents BITS from running using task scheduler by making a .bat file @echo off
   sc stop BITS
   sc config BITS start=disabled
   exit that runs when triggered by Log:Microsoft-Windows-Bits-Client/Analytic, Source: Microsoft-Windows-Bits Client and Log:Microsoft-Windows-Bits-Client/Operational, Source: Microsoft-Windows-Bits Client Can I do the same for delivery optimisation somehow? Or any other method that will PERMENANTLY prevent the delivery optimisation process?
