  If you want to disable it global, edit boot.ini and change noexecute to execute.
  
  [boot loader]
  timeout=0
  default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
  [operating systems]
  multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows XP Professional" /fastdetect /noguiboot /execute=optin

  See this Microsoft article about the limitations of DEP:
  
  http://www.microsoft.com/technet/prodtechnol/wi...
  
  Not all of it works on all processors, for example.
  
  See this enigmatic sentence:
  
  "By default, software-enforced DEP only protects limited system binaries, regardless of the hardware-enforced DEP capabilities of the processor."
  
  What are "limited system binaries"?

  To disable DEP by modifying the Boot.ini file, change the /noexecute policy level to alwaysoff.
  
  /NoExecute=AlwaysOff

  My pc would crash randomly while playing UT or looping one of the 3dmarks before this. I was getting so frustrated, so I tried this on a whim and left 3dmark 03 on all night. What a joy when I was startled out of bed by the sound benchmarks at the end ;-) It ran for over 10 hrs and I'll be testing UT soon. Thanks webworm99!!!!

  I dragged 2 x JPGs from a CD to the "My Pictures" folder. I immediately got a DEP error which forced Explorer to close.
  (Perhaps foolishly) I got the JPGs into the folder by opening them and used "save as" to put them into "My Pictures".
  Now - whenever I try to open the "My Pictures" folder - DEP stops Windows Explorer and causes it to close. But note I can still access other folders without problem.
  I've now deleted both JPGs (I had to use 'Search' to get access to the files). I deleted them from the recycle bin too. But I still get the DEP when I try to access "My Pictures".
  What can I do to fix?
  I am reluctant to disable DEP on Windows Explorer. What are the dangers?
  
  Background: I recently installed SP2. The "My Pictures" folder is large (1430 files and 1 x sub folder). I used AVG to scan the folder before I deleted the offending JPGs (no eror reported). I am running XPs firewall as installed at SP2 upgrade time.
  
  I have an option to use restore and go back 3 days - but I'd prefer to avoid this if possible.
  
  Any help/suggestions would be appreciated.
  Thanks.

  Thanks webworm.
  
  I noticed your suggestion to disable dep. But as I said - I'm reluctant to do this (even for Explorer only) as I'd loose the benefits of dep.
  
  If someone could assure me that loosing dep is not a big loss I'd feel better about the idea. (Better still - explain where the problem is and what is the fix?).

  I could not assure that this is the problem. However, Since you have xp sp2. Here are something you could try. You can always go back.
  
  Update your graphics driver (From the manufacture website not windows update.)or roll-back to the original driver you had. If you go back to the original driver, when using windows update and if it detects the graphics cards needs updating. Just hide that update.
  
  Some virus protection programs can cause this as well.
  
  Right Click on my computer, Advanced tab, Performances setting , Data execution prevention tab. Turn on dep for all program and services except those I select.
  
  You might make a system restore point before trying any of these tips.

  Spent two hours last night trying to work out why the hell my friends printer decided to stop working since he installed XP Pro on a new hard drive on a new PC (64bit Athlon).
  
  It was a HP5552 using the latest "basic" driver from hp.com, but it would not print from Windows, not even a test page. We could copy raw text to LPT1: using a command prompt just fine, but no printing from the GUI.
  
  After checking absolutely everything, I thought to check DEP to see if it was turned on - it was - his CPU supports DEP and it was fully on. Altered it to the basic setting, rebooted and voila - printer test pages suddenly started working again. 8O
  
  I'm seriously going off Windows. :(

  Hey, i dont know if im posting this in the right place, but i thought its worth a try anyway! Ive recently bought a new computer (i usually get a friend to build one for me.. but this time i found a package from evesham i coudln't resist).. but anyway.. as its been bought rather than built its come with a proper legal copy of XP. lol
  
  Im having trouble installing all my programs now (most of which are various design packages bought for around £1 in Malaysia.. i think you get what im saying here...).
  I keep getting "C:windowssystem32autoexec.nt. The system file is not suitable for running MS-DOS and microsoft windows applications. ChooseClose to terminate the application." (the ignore button does nothing)
  i know these programs all work perfectly as i have used them previously on both copies of XP and win2K.
  
  I dont know if its something im doing wrong... or theres a box somewhere i need to check, or if its something more indepth! Im not so good with this stuff haha
  if anyone has any suggestions id be really grateful cos ive got a super dooper computer i cant actually use at the moment!

  I'm seriously going off Windows. :(</ul> I've recently run into a similar situation. DEP errors were hitting me left and right; mostly inside windows explorer. Changing the radio butten (inside system properties-DEP) allows you to exclude DEP for an app (in this case windows explorer), but prevents you from printing to an HP printer (in my case the psc 1210xi). Right now my choices are to either live with the DEPs in windows explorer, OR be able use my printer.
  
  Short of disabling DEP for everything, are there any other options? If not, how do I disable DEP?

  If you can't disable DEP for the printer driver, the only other option is to disable it completely.
  
  Searching for your printer on google, I can't find anybody else having this sort of problem...
  
  Try to disable DEP completely as previously described in this thread, and see if that helps.

  Also, try adding the following:
  (Save the following as a filename.reg file if you are unfamiliar with navigating the registry. Double-click and import). I have found that some software seems to interfere with explorer.exe causing it to crash at launch (and loop).
  With the default settings however, DEP should be including explorer.exe in the "Turn on DEP for essential Windows Programs and Services only" but for some reason this fails. Adding the following apples to this default setting, but will also show explorer.exe in the exception list if you select it. See if any newly installed programs are trying to launch a taskbar item, as this is one common thread I have seen in affected machines.

  I have been unable to close the Data Execution Prevention - Microsoft Windows display that states "To help proptect your computer, Windows has closed this program. Name: Generic Host Process for Win 32 Services, Publisher: Microsoft Corporation, with a radio button "Close Message".
  
  When I click on "Close Message" the Microsoft Error Reporting Window appears and no matter whether I click on "Send Error Report" or "Don't Send" and close this window, then the DEP window appears again. And the DEP window does not stay in the background but remains in the foreground and I have to move it almost entirely off the desktop to be able to view whatever I am working on.
  
  I was on the phone with Microsoft Help Support for over 3 hours yesterday while the technical person had me go through a series of different scenarios including going back to a previous sytsem restore (3 different days); changing the boot.ini as described in some of the previous comments; removing the Microsoft security updates installed on 06/15/05, and changing the start up process in msconfig from selective start up to normal. It seemed that when I changed to the normal start up selection that the DEP window wasn't going to reappear so I ended the call with the Microsoft technical person and then low and behold about a half hour later the DEP window reappeared.
  
  The DEP problem occurred I believe after the 06/15/05 security update and I it only appeared after I shut down my computer on the morning of the 17th of June and brought it back up again that evening. I even went back to an earlier restore before calling Microsoft but that didn't get rid of it either.
  
  I was wondering if anyone else encountered this problem; and if so, how to go about fixing it.

  I have this DEP message coming out all the time when i want to go to the Control panel, I simply could not switch off or access the System function, i have also switched off some of the programmes that DEP has function on and now it seems it always turned off any function in the Control Panel, what can I do? I want to return the new Computer I bought, all the softwares I used before on other computers had no problem at all, but could not run in this new computer.
  
  the Comptuer manufacturer told me (HP) to re-run operating system, completely reinstall and re-run recovery CD, but I suspect that this DEP will come out again because it seems so sensitive to my softwares.

  One thing to plug-in the code on my drive I had to remove my drive C: and stick it in another computer and boot up to another drive. Once you do that you can plug-in the new code and save it.
  If you know a eaiser way to do that let me know but I am impressed!
  Thank You for now I can do what I want on my own computer without DEP locking me out of any of my files.
  Yes, it is completely shut off and thats GREAT!

  I ran across this at work with one of our computers and a website that needed an ActiveX controller installed. What I found was that this PC was missing the Autoexec.NT file altogether. I simply copied the autoexec.NT file from my PC and pasted it to my users and it worked find. You can also copy this file from the WinXP CD I believe it is in one of the CAB files and Microsoft has a something in their KnowledgeBase on how to extract files from CAB files.

  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.

  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.

  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?

  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.

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