I'm stuck in this ridiculous Vista DEP loop, which kicks in and closes I.E. 7. No new hardware or software hgas been installed. I've run malwarebytes, trend micro and spyware doctor; the machine comes up clean. I've ever fixx I could find, management console setting, command prompts (bcdedit.exe). Nothing seems to work. Any ideas? Thanks.

This should cure the I.E. crash problem

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.
