I've taken every measure to disable Vista's Data Execution Prevention from shutting down an application that I am being forced to use (it's called GameGuard, used in some Asian MMO's for anti-hacking).



I've tried disabling DEP through the Vista GUI by adding exceptions and I've tried disabling through the command prompt with the guide posted on this site. When I go to the DEP menu in Vista it's all greyed out now which supposedly would be signifying the inactivity of DEP. To no avail, however, as GameGuard continues to be forcefully terminated by Vista while showing a DEP notice.

Has anyone figured out how to get rid of this Vista feature?

I'm currently running it as Admin also tried XP SP2 compatibility mode.

You can disable it in Vista completely. I would leave it running in BIOS. I use this method and DEP does not affect any of my apps anymore but the hardware level DEP does protect from outside access.

I've yet to try disabling it in BIOS but the software side is completely disabled.




And here is the message I get after it forcefully crashes GameGuard:


I guess my last resort is running it in a VM but I'm close enough at this point to reformatting and just going back to XP.

Right click on command prompt in accessories, run as administrator. In the box

bcdedit.exe /set {current} nx AlwaysOff

This will disable it in Vista. Turn on NX in BIOS.
