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

Contributed by MickeyMouse

Tagged: Windows

No-execute and execute protection are all names for DEP. This process feature increases security, but may cause problems with certain programs.

Several OSs have no-execute or execute protection. Microsoft has added this as well in SP2 with data execution prevention (DEP). This precents 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 that is the cause. Here are the steps. (Just disable DEP for the program in question… don’t disable it for your whole system.)

Start

Control Panel

System

Advanced

Performance

Settings

Data Execute

Turn on DEP for all programs and services except for those I select

Add

Open

Apply

Hah-hah – DEP has rendered the opening of windows INCLUDING Control Panel – impossible. Oy – woss macht man dann!?! (any ideas, PLEASE – Dunno what made that click in!)
Taavi said on March 1, 2009

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…
if anyone has any ideas, please let email me (since I may not check this post): t.tillmann [at] ucl [dot] ac [dot] uk

Thanks,

Taavi

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

JerryW said on May 3, 2009

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.

hello, i’m using vista home premium, DEP keeps crashing internet explorer 8 whenever I start it, I added it to the list of programs I want it disabled for, then I restart, Internet explorer is still blocked by DEP and the settings for it have reset, this has happened 6 times!
JerryW said on May 4, 2009

Sounds like you need to stop DEP from executing, done by editing boot.ini. My post above and earlier ones give instructions.

I have tried the cure to no avail , everytime I want to print off the internet windows xp shuts down my canon LBP-1120. I have tried the canon patch but everytime I try to open CAPTRU utility (cap3ru). I get the message’ It is of off the subject of this schedule.’ I am going nuts?
What is the solution????
Rob said on May 19, 2009

Help, I upgraded IE on XP SP3 and cant close webpages unless i use end task on Windows Task Manager. I have tried stopping DEP on IE but still will not allow me to close pages when on internet. Any ideas?

Thanks,
JerryW said on May 20, 2009

Which cure did you try:
Cure 1: tell DEP to leave a particular program alone
Cure 2: prevent DEP from running

Are you sure you have a DEP problem? If you are, try the other cure.
JerryW said on May 20, 2009

Throughout the list of comments, many people report that Cure 1 (see above) simply does not work for them. That leaves Cure 2. I had to go with Cure 2. As above, are you certain DEP is the source of your problem?
JerryW said on May 20, 2009

PS – Why aren’t you using Firefox?
brian said on May 20, 2009

I tried cure 1 the exception nmethod, ok will have a go at stopping DEP completely

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.

Grajgajgr said on June 10, 2009

….This isn’t turning it off.. You’re better just leaving it to the default which covers only system processes and services. Unless you feel like browsing for every last application you want to use without DEP and adding it to the list like this guy suggest.
JerryW said on June 11, 2009

Solutions to these problems are described further up the list. Do some reading.
JerryW said on June 13, 2009

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.
JerryW said on June 17, 2009

It depends on when your computer is shutting down. Can you see the START bar? If so, follow the procedure I describe in my following post. Worst case might be reinstall of the operating system.

WindowsXP Home Edition: I am trying to access an online site and DEP is blocking me. When I go to disable DEP, I cannot add the program I am trying to log into because it’s a website, not actual software. This is a secure site for goverment work so I know it’s not harmful. Any suggestions?
JerryW said on June 23, 2009

Are you using IE? Looking through the comments list, you can see several people having trouble with IE and DEP. Try Firefox. If the problem persists, you might have to stop DEP from running. See above for instructions.

DEP is the biggest piece of crap i have ever seen. Cant even use the computer now it always shuts IE down even though i have added it and restarted. is there any way to remove it all together i don’t care any more microsoft can go to hell
JerryW said on July 1, 2009

I recommend you do not remove it. Just change the boot.ini file so DEP does not execute. Instructions are above.

Frustrated with Microsoft! said on July 30, 2009

I had problems with running the program Anonymizer, each browser I used along with it was shut down by the DEP, tried adding the exception with no luck. Till I followed these instruction by Anonymous… rebooted, ran Anonymizer and the browers and it worked perfectly! Thank you very much.
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 do i Disable the DEP with the Task Manager?
Anonymous said on August 31, 2009

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.

Skippy said on October 10, 2009

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.

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.
Ryann said on February 18, 2010

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!

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?

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?
