XP SP2: How to Turn Off the Data Execution Prevention feature (DEP)

No-Execute and Execute Protection are all names for Data Execution Prevention (DEP). This process feature increases security, but may cause problems with certain programs. This tutorial explains how to disable DEP when such problems occur.


Several OSs have No-Execute or Execute Protection. Microsoft has added this as well in SP2 with Data Execution Prevention (DEP). This presents code execution in memory regions already marked as storage. This is a powerful tool against buffer overrun exploits.

If a program is failing and you want to disable DEP to see if it is the cause, use the following steps. (Just disable DEP for the program in question. Do not disable it for your whole system.)

    1. Click Start.
    2. Select Control Panel.
    3. Select System.
    4. Click the Advanced tab.
    5. In the Performance region, select Settings.
    6. Click the Data Execute tab in the dialog box that opens.
    7. Select Turn on DEP for all programs and services except for those I select.
    8. Click Add.
    9. The open dialog box will open. Browse and select your application.
    10. Click Open
    11. Click Apply
    12. Click Ok
    13. Reboot

      Hey Chaim,

      I am having the same problem after I tried to install a suspect KeyGen.
      I want to install virus-scanner, to see if it could remove it. but i can’t even install programs, DEP pops up again…
      U have the same issue?

      Have you tried using “Rocko”‘s suggesion from 2 years ago? I’m too scared to do it myself.

      I’m considering formatting my hard drive and starting from scratch…

        Like most people here, I am having a problem. After some software tried to install itself on my computer, first I got a warning message from my spyware protector, then got the Data Execution message: boot acceptance application for registry.
        Now everytime I turn on the computer it goes into safe mode, and the warning message comes on again.
        Running XP Pro with 2006 Service Pack
        Any suggestions? I’ve just run CCleaner but no difference

    If DEP has hung up execution without the START bar, you can get that going via Task Manager (ctrl-alt-delete). From Task Manager, select the Applications tab, then New Task. Browse to: Docs – All Users – Start Menu – Programs – Accessories – System Tools – Scheduled Tasks.lnk. With Scheduled Tasks.lnk showing in the Open field, click okay. The START bar will start, and you can follow the procedures described in earlier posts to kill off the dastardly DEP.

    Hint: make all hidden files visible so you can see boot.ini. If boot.ini is still not visible, open File Manager to the root directory, place the mouse immediately below the listed directories, where boot.ini would be visible if it was visible. Right click on that space and deselect the Read Only property for boot.ini. With the START bar available, you can use a text processor to edit boot.ini (you are using Notepad++, aren’t you?)

    I was successful changing “/noexecute=optin” to “/execute=optin”. Deleting just 2 characters will isolate DEP, a fate it deserves. Don’t forget to reset the Read Only property for boot.ini after it is saved.

    If ctrl-alt-delete does not start Task Manager, you can use some links on the DEP warning dialog to get the START bar going. Click Debug and Visual Studio will open for you. Ctrl-alt-delete might now start Task Manager. You can also get IE or Firefox going from the warning dialog by selecting More Information or something like that. With IE/Firefox running, Task Manager should be available.

    My thanks to the early posters whose notes helped me get going again with XP-P.

      Dude I have done all the steps to Disable / isolate DEP.

      >
      1. Open Windows Explorer
      2. Tools > Folder Options > View
      3. Uncheck “Hide Protected operating system files (Recommended)” and “Hide extensions for knows file types”
      4. Click apply, and OK
      5. Go to c:
      6. Right click on boot.ini, select properties and ensure the “read-only” tab is unchecked and click OK
      7. Double-Click boot.ini
      8. Modify /noexecute= for example /noexecute=AlwaysOff to disasble completely
      9. File > Save As
      10. Filename: “boot.ini” (with the quotes) Save As Type:All Files Encoding: Ansi
      11. Select Replace the oroginal “boot.ini”
      12. After Saving, close file.
      13. Right click on boot.ini, select properties and ensure the “read-only” tab is checked and click OK
      14. Reboot

      *On the step 8. also I have changed “/noexecute=optin” to “/execute=optin”

      This worked for a lot of people people, but in my case Even if i have isolated DEP i try to enter a folder with 200 videos inside, No proble while i am in the folder but when to play one of them explorer restarts. Its fucking terrible thing.

      *If it help i spoted that in my computer in the “boot.ini” the “/noexecute=otpin” was “/noexecute=otOut” by default. I changed to “opIn” Matters of something?

      HELP!!!

    I need help, please. I tried to disable DEP by trying to open the system in control panel, but the problem is, DEP won’t allow me to open it, the same goes when I try to use the reboot.ini method and when I try to open ‘Properties’ by clicking on My Computer. DEP says ‘To help protect your computer, Windows has closed this program. Name: Run a DLL as an APP, Publisher: Microsoft Corporation.’ I can’t even open Add or Remove Programs. What other ways can I do? I really hope someone can help me with this.

    I suggest you do not attempt to use Add or Remove Programs to remove DEP. Use only Cure 1 or Cure 2 described earlier.

    If you cannot see the START bar, look back to my first post for approaches.

    If you can see the START bar, but cannot otherwise get going, try this:

    - Click on Start – Run, then enter “explorer.exe” in the Open field and click OK or hit Enter.
    - Using Windows Explorer, select My Computer and C:, then:
    - Select: Tools – Folder Options – View, then:
    - – select: Show hidden files and folders
    - – unselect: Hide protected operating system files
    - – click OK

    - Next, select the boot.ini file, Right Click, then click Properties and deselect Read-only, then click OK. Now you can edit the boot.ini file.

    - Click on Start – Run, then enter “notepad.exe boot.ini” in the Open field and click OK or hit Enter.
    - When the boot.ini file opens in Notepad, change “/noexecute=optin” to “/execute=optin” and Save.
    - Close Notepad and Restart your computer from the Start button, or use Task Manager (ctrl-alt-delete), select Users tab and Logoff – Restart.
    - When your computer restarts, use Windows Explorer as before, but set boot.ini Properties back to Read-only to protect that file. Hopefully, your DEP problems are now over.

    If DEP prevents you from doing the above, take a deep breath, relax, you are going into the Command Console as a desperation move:
    - Click on Start – Run, then enter “cmd.exe” in the Open field and click OK or hit Enter.
    - When Command Console opens, type “cd C:” then Enter. You should see “C:>”
    - Type “explorer.exe” then Enter. Follow the instructions above to deselect Read-only for the boot.ini file. Return to the Command Console window.
    - Type “notepad.exe boot.ini” then Enter
    - When the boot.ini file opens in Notepad, change “/noexecute=optin” to “/execute=optin” and Save.
    - Close Notepad. Return to the Command Console window.
    - Type “exit” then Enter.
    - Restart your computer from the Start button, or use Task Manager (ctrl-alt-delete), select Users tab and Logoff – Restart.
    - When your computer restarts, use Windows Explorer as before, but set boot.ini Properties back to Read-only to protect that file. Hopefully, your DEP problems are now over.

    If all else fails, you might try a reinstall of the operating system, then before doing anything else, edit the boot.ini file to isolate DEP…BEFORE running any other applications.

    If DEP is giving you serious problems, it is because DEP is not compatible with your CPU. Either upgrade the CPU or isolate DEP. The instructions given at the top of this file will not be adequate.

    If you are using IE, don’t forget to install Firefox and make that you default browser.

    BTW why does windows screw up with DEP being so incompatible with so MANY programs. Before launching new programs like Vista, FIRST make sure previous Windows versions are working smoothly, thats what you rake in the millions for so do your JOBS properly. We should not have to search sites like these to FIX there mistakes.

      How about somebody just answering the question. I have a similar problem and this forum just wasted a lot of time not giving an answer – just everybody asking the same question over and over and a bunch of “maybe” answers, none of which work. My DEP will not turn on or off. It gives the same window as mentioned except none of the settings will stay. None of the changes to the boot.ini do anything. Turning on or off the reporting service does not stop this from happening. There are no viruses or adware detected with any softwares used.
      The question is how to eliminate DEP – not how to turn it off. Nothing in the BIOS says the board or chip has it by any name. This just started in the middle of some work without any internet connection. The programs had been installed and running for months fine. This is not on a network machine. It does not take in data – it is a production machine, disconnected from everything.

    Do you realize what you’ve just lost? This is supported at the processor level and you WANT it.

    Data Execution Protection (or the No Execute aka NX bit) is there to prevent applications from modifying memory that has executable code in it. A relatively easy attack is to find a buffer overrun in some string handler in a commonly installed application, like an HP or Epson printer driver, Flash, etc. If I can figure out in a debugger that their app is actually modifying its source code in some way, then I can just manipulate the inputs to get it modify its executable code in such a way that it will point at my input value, which is actually the source for an exploit. If DEP/NX it turned on, then applictions are prevented from modifying the memory allocated for code and thus this class of exploit is not prevented on the machine.

    Oh, there is no mechanism to disable DEP for a 64-bit process, which is almost every built-in app in Windows on a 64-bit version of XP, Vista, or Win7. WMP, IE, and a couple others actually run 32-bit versions by default for compatibility reasons.

    FOR ALL VISTA USERS !!!!
    this will work guaranteed, no stupid boot.ini file to search (wich vista doesn`t have anywayz so good luck with that) i found it on a computer journalists website.
    please follow all instructions and you will not have to worry about the dep again..
    also instructions to turn back on. Instructions to follow now:

    Disable
    1/ Click the Start Button

    2/ On the Start menu Click All Programs

    3/ On the All programs menu Click Accessories

    4/ From the Accessories menu Right Click on the Command Prompt and, from the drop down menu, Select ‘Run as administrator’

    5/ If the User Account Control feature pops up you will need to either press the Continue button or else provide UAC with the details it requires

    6/ When the Command Prompt window opens type: bcdedit.exe/set {current} nx AlwaysOff and press Enter (dont forget to use the spaces in the line)

    7/ If all has gone well you should see a message saying that ‘The operation completed Successfully.’

    8/ Close down the Command prompt window and Restart your PC for the changes to take effect.

    Enable
    If, at a later time, you want to re-enable DEP proceed as follows:

    1/ Click the Start Button

    2/ On the Start menu Click All Programs

    3/ On the All programs menu Click Accessories

    4/ From the Accessories menu Right Click on the Command Prompt and, from the drop down menu, Select ‘Run as administrator’

    5/ If the User Account Control feature pops up you will need to either press the Continue button or else provide UAC with the details it requires

    6/ When the Command Prompt window opens type: bcdedit.exe/set {current} nx AlwaysOn and press Enter

    7/ If all has gone well you should see a message saying that ‘The operation completed Successfully.’

    8/ Close down the Command prompt window and Restart your PC for the changes to take effect.

      I’m running on Vista and DEP was closing down almost everything which was a major pain in the ass. All this started around Nov 09 as a result of one of the upgrades. I’ve read through a lot of recommendations but for me, a novice, the one that worked best was to get a program called the Ultimate Windows Tweeker that someone recommended. All you have to do is load it, go to systeme performance, and then click on “Turn off DEP”, Yes it cost me $35 or so for the program but all my DEP problems are a thing of the past and I can actually use my laptop again and for me the 35 was well worth it. And no…I have nothing to do with whoever sells the program only throwing in my 2 cents since having DEP active on my PC was the worst thing that has attacked my PC!

      I tried this, to absolutely no result. The program I’m trying to run still wont work. Also, what do you mean by {current}? Because it didnt say it was succesful until I got rid of it.

      Ignore that, it had a result. It crashed my computer, and took about 9-10 hrs to even access internet! Thank you for completely ruining every executable file on my computer, and stopping me from turning DEP back on! Now I can do nothing but sit here and hate you!!!

    I can’t seem to even add the program onto the list, it says that “This program must run with DEP enabled. You cannot turn off DEP for this program.” But it is a program I trust..

    jesus christ fucking windows, i find myself here simply because im getting stinking dep error messages when i play MY ILLEGALLY PIRATED DIVX MOVIES FROM TORRENTS SITES thats right, and i dont giv two shits neither, im clearly getting this stinking crappy typical bill gates ponce move top try and stop piracy, and as there is no clear way to disable dep, seen as it is selected for 0 programmes on my pc anyway, and is only happening in /videos sub folder, the clear answer to me, uninstall stupid crappy sp2 all together, because frankly, all these poxy stupid updates, and my computer and security worked fine without them. SAVE A PC, SHOOT BILL GATES.

    So I did that and was excited because well my schoolwork was what was getting DEP . (I have a computer based school program.) Well after I did that I can’t get onto my computer. I use vista (not by choice) but it loads up until it gets to the login screen then it stays black with the cursor. Any input on this?

    I’m trying to add windows media player to the DEP “allow” list, but it will not allow me to add it. Saying windows must be used with DEP. What should I do now? I’d like to know how to shut it off completely as it doesn’t seem to let me run any of my editing programs. I’m not really technically inclined so I don’t understand the command prompt way of disabling it either.
    Thanks

      For all above issues turn it off in the BIOS setup – set to disable. Its too intrusive so just disable it – problems gone!

    I don’t understand it when I’m told DEP is necessary. How can a security programme be necessary which itself acts like a virus? Who-ever came up with this one has made a complete mess of it, and should now be dealing with it as a matter of urgency, and not letting those who are struggling to cope suffer any more of this stupid incompetence. Meanwhile, will some-one who thinks DEP is a good idea tell me exactly why my other, highly successful, security measures won’t cover the problems not having DEP might cause?

    To disable/isolate DEP :

    1. Open Windows Explorer
    2. Tools > Folder Options > View
    3. Uncheck “Hide Protected operating system files (Recommended)” and “Hide extensions for knows file types”
    4. Click apply, and OK
    5. Go to c:
    6. Right click on boot.ini, select properties and ensure the “read-only” tab is unchecked and click OK
    7. Double-Click boot.ini
    8. Modify /noexecute= for example /noexecute=AlwaysOff to disasble completely
    9. File > Save As
    10. Filename: “boot.ini” (with the quotes) Save As Type:All Files Encoding: Ansi
    11. Select Replace the oroginal “boot.ini”
    12. After Saving, close file.
    13. Right click on boot.ini, select properties and ensure the “read-only” tab is checked and click OK
    14. Reboot

    *On the step 8.You can change “/noexecute=optin” to “/execute=optin” it will isolate DEP.
