Annoyance: Turning off DEP in Vista

Posted: Sun Aug 03, 2008 2:38 pm

If you are trying to run an installation or other executable being stopped by DEP, it could save you some trouble so turn it off while you attempt to give it another shot…

Run a command prompt as administrator. From the start menu, select "All Programs", then "Accessories" and right-click on the "Command Prompt" shortcut and choose "Run As Administrator". From here you can use the following command to disable Data Execution Prevention (DEP) with the following command:

bcdedit.exe /set {current} nx AlwaysOff

Keeping your command prompt open, run your setup or other process being stopped by DEP. Then, to turn it back on again, do the same and run the following:

bcdedit.exe /set {current} nx AlwaysOn

>>> Should look like this<<<<<<<Microsoft>bcdedit.exe /set {current} nx AlwaysOff
The operation completed successfully.

C:\Windows\system32>
