Several years ago it was difficult to use the DEP capability provided by
modern hardware because both older programs and the OS played silly
tricks to save a microsecond here and there. I, like most of you I
presume, only turned on DEP capability for OS functions. My question is
what is recommended for today given that I'm no longer running all those
old 95, 98, and XP programs that I thought I couldn't live without? Is
it now standard to turn DEP on for everything? It's been years since
I've seen any discussion of this topic and I'd like to get caught up.

You could use EMET. It went out of support in July
of this year. It comes with a user manual and
a few "standard" profiles.

"The security mitigation technologies that EMET uses have an
application-compatibility risk. Some applications rely on
exactly the behavior that the mitigations block."

The age of the software isn't the only determinant. There
are modern software products, where the company making
the software, suggests turning DEP off for it.

I had DEP turned on for a time here, in WinXP, and
I started getting random applications tripping it.
I think that might have been my memory problem on
this machine that was doing it (memory since replaced).
