Can't turn on DEP

[Victek]

I'm running Windows 7 x64 and tried to change the DEP setting from the default (essential windows programs and services) to all applications. But after the reboot the setting is back to the default. Any idea how to troubleshoot this?

Yes that's exactly what I did with the exception of adding a program to the exclusion list. I don't have a reason to turn DEP off for a particular application.
