Windows 10: Difference Between Exploit Protection DEP & Performance Options DEP

When I was playing around with some settings in Windows Defender, I noticed that there is a setting to turn on/turn off DEP in the Exploit Protection settings section. I've had trouble with DEP on Windows 7 so I ran the following command to disable it completely: bcdedit.exe /set {current} nx AlwaysOff

When I installed Windows 10, I didn't check to make sure that DEP was still disabled. Today I noticed a setting in Windows Defender where DEP was turned on. Naturally, not wanting this feature, I turned off the setting and rebooted. Then I thought about the DEP in Performance Options and was wondering if my turning off the DEP in Windows Defender also disable the DEP in Performance Options, or if they are unrelated and when I upgraded to Windows 10 that it saved my setting to disable DEP from Windows 7. So what exactly is the difference between the two--if any at all?

DEP errors make webpages unavailable

Hi Richard,

Data Execution Prevention (DEP) is a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits. You can turn off Data Execution Prevention for a particular program in Windows by following
the steps below:

• Open File Explorer.
• Right-click on This PC, choose Properties and then click on the
  Advanced system settings link.
• Now click on the Data Execution Prevention tab and you’ll see two radio buttons. By default, DEP should be set to the first radio button and therefore only protect essential Windows programs and services. If the second radio button is selected,
  it will turn on DEP for ALL processes, not just Windows processes.
  
• Since you’re having issues with your browsers, go ahead and try to select the first radio button, restart your computer and see if that fixes the issue. If not, you can go ahead and click the Turn on DEP for all programs and services except those
  I select button and then add the program that is having problems. Make sure to also check the box.
• Click the Add button and browse to the location of the executable for the program you want to remove from DEP protection.

DEP unclickable


​Long story short, I have been trying to play a game I downloaded from the internet and my laptop has been refusing to play it and the game just wont work, because it is a 16 bit program trying to work in a 64 bit computer. After some research I finally figured out how to fix it, and that is to go into advanced settings and click on data execution prevention and click on Turn on DEP for all programs and services except those I select.
I was thrilled that I found it till it turns out that I cannot click on anything as an option. Near the bottom it is telling me "To use these settings, you must be a computer administrator and you must use the bcdecdit.exe file. For more information, search the Microsoft Knowledge Base online." before you suggest that I already did and nothing has helped. Please help me figure this out, it would be much appreciated. I uploaded a picture to show what it looks like as well.
