Not sure it's relevant for newer versions of 10 but for 1607 try the below steps and it should stop it.
1. Open "service.msc"
2. Stop Security Center service and set it to "disabled"
3. Go to "C:\Windows\System32"
4. Take ownership of files "ActionCenter.dll" and "ActionCenterCPL.dll"
5. Get full access for the files "ActionCenter.dll" and "ActionCenterCPL.dll"
6. Rename the files "ActionCenter.dll" and "ActionCenterCPL.dll" to "ActionCenter.dll.bak" and "ActionCenterCPL.dll.bak"
Restart

I did as suggested above though after an sfc/scannow the files(new) were reloaded. In this case I had to redo the process.
