We have already seen how Data Execution Prevention, a security feature can help prevent damage to your computer from viruses and other security threats. Harmful programs who try to attack Windows by attempting to execute code from system memory locations reserved for Windows and other authorized programs, are stopped. These types of attacks can harm your programs and files. DEP can help protect your computer by monitoring your programs to make sure that they use system memory safely. If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you. It is as such a security feature.
While it is not recommended, you may have your reasons for wanting to disable Data Execution Prevention on your Windows computer. Lets us see how to disable DEP in Windows 10/8/7 using the bcdedit.exe tool.
Disable Data Execution Prevention
In Windows 7, type cmd in Start Search. Right click on search results ‘cmd’ and click on Run as Administrator. Windows 10/8 users can also open an elevated command prompt window via the WinX menu.
Then, copy paste the following and hit Enter:
bcdedit.exe /set {current} nx AlwaysOff
Reboot.
You will find that Data Execution Prevention has been disable on your Windows computer. You may then, if you wish, verify the status of Data Execution Prevention feature on your system.
Enable Data Execution Prevention
To enable back DEP, type the following in an elevated command prompt and hit Enter:
bcdedit.exe /set {current} nx AlwaysOn
This will enable back Data Execution Prevention.
See this if you receive The boot configuration data could not be opened message.
- Enable or Disable Data Execution Prevention (DEP) for Internet Explorer only
- Turn Off or On Data Execution Prevention (DEP) for Individual Programs.
Thank you!
I followed your command on cmd with ‘open as admin”..But it shows “An error has occurred setting the element data.The value is protected by Secure booy policy and cannot be modified or deleted.”
Thank you so much!
You are welcome. 🙂
If you’re using Windows 8 or a UEFI boot instead of BIOS, you have to disable the Secure Boot function before this will work.

You have to run the command prompt as an administrator. Open the start menu, type CMD in the search field, and wait for cmd to pop up. Right click CMD and select “Run as Administrator.”

To enable the options back, you must run this code on command prompt with administrator access
type bcdedit.exe /set {current} nx AlwaysOn, press enter
then type bcdedit.exe /set {current} nx optin, press enter
restart PC to take affect

Mine says The boot Configuration data store could not be opened Access denied. Help please?
i still end up with this
http://gyazo.com/054c362695f261f874a8db0dd3ea3376
And if that fails (AND your system is based on EFI rather than a more traditional BIOS setup), temporarily flip the switch on Secure Boot, make the changes and restart. Once back up, flip the switch on Secure Boot and you’re done!
Additionally, if the use of the {current} modifier gives you errors, simply edit it out and try again, like so:
bcdedit.exe /set nx optin
bcdedit.exe /set nx AlwaysOff
That’s what I had to do when I started using the Windows 10 Insider beta as my primary OS. Anyway, hope that helps anyone.
I love u mate. 😀 u help me a lot 🙂 i fight with that almost hour 🙂 God bless u
I wish I had a normal problem to fix so be thankful if you have a solid no or yes from your computer. Mine says it performs the bcedit operation but if I check it didn’t . Reboot its still off. Its like working with a guy that don’t listen. Just shakes their head and says yea yea yea, I got it. Never actually does anything you tell them though.
bcdedit.exe /set nx optin
bcdedit.exe /set nx AlwaysOff windows 10

Thank you very much. This method worked fine for me on Dell Latitude E6400 laptop. Spent two days to find correct solution. Thanks again.
I will name my first born after you!
Is there a way to read the current status of DEP?
I get this error.
The integer data is not valid as specified.
Run “bcdedit /?” for command line assistance.
The parameter is incorrect.
I did the “bcdedit.exe /set {current} nx AlwaysOn” and “operation completed successfully” but DEP radio buttons are still grayed out.
