Data Execution Prevention - Internet Explorer

Data Execution Prevention can be turned off completely, but it's kind of a pain.  If you find that it's only interfering with Internet Explorer, then this is any easy fix.

Symptoms:  Either Internet Explorer quickly shuts down on its own or you see the following window appear when trying to open the browser:

1.  Go to Start > Run and type the following:  inetcpl.cpl

2.  Press OK and the Internet Explorer Options window will appear.

3.  Go to the Advanced tab.

4.  Uncheck "Enable memory protection to help mitigate online attacks*"  (It's near the bottom)

5.  Click OK and Internet Explorer should open just fine.


  1. Be advised this solution does not work in Windows Vista. The selection is grayed out. The box is checked and the checkmark cannot be removed.

  2. See for an explanation of the security risk of doing this.

    To "Anonymous" above, you need to run the Control Panel as Adminstrator to ungrey the checkbox.

  3. I have Windows 7 and DEP KEEPS CLOSING Internet Expolorer before i open it. Help?

  4. Updating java worked for me
