[ Fixed ] Data Execution Prevention Error In Windows

by Abhishek Bhatnagar on March 23, 2009



One of our readers Sandip submitted a problem saying:

On my computer one error is giving that "Data Execution Prevention Error", "Windows Explorer" error is giving repeatedly.

On Exploring the options which are provided by the Windows I could find out the way in which this problem can be fixed. But before the fix, lets talk why this problem is coming.


Data Execution Prevention or DEP is a method by which the execution of suspicious softwares is prevented at the hardware level. This is done to make the computer secure against Virus Attacks. Some softwares which are not made according to DEP get errors. Lets see how we can prevent.


To fix Data Execution Prevention Error, you need to know which application is getting DEP error. For example if I get a Data Execution Prevention Error on running XYZ.exe software, then I need to add this XYZ.exe software to Data Execution Prevention Exception list. This is a list of applications which will not be stopped or suppressed by DEP feature.


Make sure that the application you are adding is trust worth and does not contain a virus. To add the application to DEP list:

1. Right click on My Computer > Properties > Advanced Properties.

2. Go to Advanced Properties > Performance >Data Execution Prevention tab.



3. On Data Execution Prevention tab you can see the first option Selected to “Turn on DEP for Essential windows Programs and Services only. Set is to the second option, press Add button as highlighted in the image below , and add the programs that give you DEP error. Be sure that you trust the programs you are adding to this list.



4. Press Apply and OK

This is it, now restart your computer and Data Execution Prevention Error will be fixed for the added applications.

My computer with Windows XP Service Pack 2 doesnt work. when i switch on the computer it hangs by displaying the message Data Execution Prevention Error – Task Manager has been disabled by your administrator.

At this point i attempted to press ALT+Ctrl+Del for several times. alas at final i got it. but no process is displaying.
any how i can go through new task and run the cmd command.

……….story goes on………..

How can i get back the start menu and desktop from the beginning it self. is it the work of a virus? then what virus?. how my administrator facility is hijacked?

Please tell me solution at the earliest.

I am having this issue with my ViewMgr, and I cannot seem to correct it using this suggestion, because I cannot find the file to add it to the list.

Hi, Whenever i try to open a program (eg. Internet Explorer, Skype etc.) It gives a DEP error and i have to include that program in the list of exceptions. But i believe this happens b/c of a Virus, so i want to know if theres some fix available for this. I cant include every single program and it gives on DEP error msg again and again.

These instructions don’t include how to tell what program is causing the DEP error. so this does not help, and is dangerous for those who don’t know how to find the triggering program. Where is the link to explain how to find which program is causing the DEP error???
