DEP

Hello. So i went to windows 10 because my cod 4 hacking days were over. Now that i regret it and want to go back i need to disable my dep. I have tried everything. I went to computer properties, advanced then tried and turn it off for the specific hack but it wont let me. When i run it as admin and type bcdedit.exe /set {current} nx AlwaysOff it doesnt allow me to do so. Does anyone have another solution?

What executable are you targeting?
