Vista: Disable DEP or NoExecute Protection to fix Explorer Crashing
Posted by Hack_Vista in Microsoft Vista
Some explorer crashes, especially in the early builds of vista, are due to DEP violations. Turn it off and see if it helps.
DEP or NoExecute Protection will be a vital part of vista security. During these early builds, however, it can lead to many explorer crashes.
If you are getting a lot of explorer crashes, disable it and see if it helps.
Disable DEP in Vista:
1. Click Start
2. Click All Programs
3. Click Accessories
4. Right Click on Command Prompt
5. Left click on Run as Administrator
6. Click the Allow button if it asks you for permission
7. Type or copy and paste this into the command prompt window:
bcdedit.exe /set {current} nx AlwaysOff
8. Hit enter and you should see the confirmation: Operation Completed Successfully
9. Reboot and DEP should be off.

I’ve DEP shutting down my spooler so that the printer does not work. I no longer get the message on start up but the spooler is always off. This in XP though. What has suddenly started this? I cannot get the spooler to start manually either. Bit of a drag as you can usually print your help before starting the fix, I have to write everything down!

You didn’t run it as admin, try again and follow directions better.

Not very useful. I did it but to no avail: caused more trouble. I reinstalled avgfree and ran a disc check on C drive which solved my problem.

i know this might be an easy fix but i turned off DEP because it was blocking a program and the DEP is still stopping it from running. any ideas?

I had same problem with Vista Home running IE8. I disabled Google Toolbar add-ons and all is OK now. (Right click Internet explorer, select start IE without Add-Ons – if this works you can then go to Manage Add-Ons and disable individual ones. I disabled the most recently intalled ones and by a process of elimination discovered that it was Google Toolbar and Google Findbar which were the cause of the problem)

Thank you so much! You totally helped me fix my problem. I disable all Google items and then I was able to see the items on the websites I needed to see. No one else seemed able to help me. Thanks again!

I typed in the command in the command prompt and it disabled DEP but the program it kept blocking still doesn’t work. Do you know what I can do to get the program working?
June 05, 2009 at 8:06 pm, Ross Wilson said:
to reverse this do the same as above but type : bcdedit.exe /set {current} nx OptIn into the command window
June 09, 2009 at 11:42 pm, Jeff said:
When I run the command i get:
“The boot configuration could not be opened. The maximum number of secrets that may be stored in a single system has been exceeded.”
Any ideas on that?

I disabled DEP as you described with bcdedit.exe command line entry. The problem was not solved and I cannot restart DEP with bcdedit.exe /set {current} nx AlwaysOn. So, now I sttil have the problem and no DEP support. What now?

DEP is a bit of security from windows (thhat i find annoying because it closes all my fav apps all the time, i do have to restart app after diabling for program) that closes programs using to much memory, or something. When a program does something windows doesn’t like, DEP(data execution prevention) closes it.

Hiii,I did as it is and now it is working perfectly.But am shutting down by DEP for all the essential Windows programs….

FOR THOSE WHO WANT TO GO TO THE DEFAULT DEP!
1) Right click on cmd : Run as Administrator
2) type : bcdedit.exe /set {current} nx Optout
3) Restart pc
4) Everything back
5) DONT EVER TRY AGAIN the : nx [AlwaysOff OR AlwaysOn]
Thanks! I hope you all be alright!

I cannot fix the Data execution prevention no matter what I do, my hubby can check his email without getting these notifications, from the same computer.

Thank you ChezzaX! I really appreciate your suggestion but I got it fixed, had to pay for it (charge) it took two days of chatting with the East Indians but it turned out to be Internet Explorer 8, This computer, an HP came with Explorer 7 and because of my constant and annoying updates, I downloaded Explorer 8, Big mistake! DEP is such a pain, there are many suggestions for fixes on here, hope anyone else chooses the right one.

when you get to the CMD on the accessories list dont click on to it, instead do a right click and select to rum CMD as an administrator- then copy and paste as per point 7 above-
Running CMD as a “User” does not give the the permissions you need!

I am using windows vista home edition. Recently I upgraded Internet Explorer. Many windows are opened while browsing various web sites and if any one window is closed by me, instantly all other opened windows are closed.
I believe it is part of DEP program introduced by Microsoft. I executed your command as administrator and rebooted and the problem is solved.Thanks for the help. Any program should not override user options. Beyond the intendented purpose of the program it becomes a pain in the neck for the user.

I know this was some time ago, but I just did a clean install on new hard drive…I kept getting the error, followed your instructions and now my computer won’t boot up – not even in safe mode. I am running a “Pre-boot system assessment”. Any suggestions? By the way, I JUST got done updating the Vista Service Pack 1 which I see from others posts that it’s not compatible….wish I would have seen that sooner.
