Who the hell had the stupid idea of inventing DEP??????????????

Now i´m not a PC techy kind of guy but i just splashed on loads of money on a
new laptop with vista and most of the prog's that i though would were
excelent do not run on vista due to the the brilliant DEP. What the hell is
that ??? I can't turn it off, does not allow me the owner of the comp. to
turn off the files i want.... what the hell is microsoft trying to tell me
how to use my PC??????

Pls Reply if you also have prob's with your DEP if number becomes large
enough may be bill gates will notice )))

Disable DEP in Vista:
Type or copy and paste this into an elevated command prompt window:

bcdedit.exe /set {current} nx AlwaysOff

Hit enter and you should see the confirmation: Operation Completed Successfully
Reboot and DEP should be off.

Use bcdedit.exe /set {current} nx AlwaysOn
to turn it back on.

You can disable it if you like, as others have explained.

But it isn't a stupid idea, it's a great idea. It gets over a serious flaw
in the von Neumann architecture (i.e. code and data sharing the same address
space, which has obvious security and reliability implications).

If you are having problems with DEP then as others have mentioned you can
turn it off. This is only fixing the symptom though and not the problem. The
program or driver causing the DEP errors is still running and may cause
other problems. Can you post the details of a couple of the errors?

In addition to the other replies ....

Data Execution Prevention is a common feature in ALL modern operating
systems.

Linux has supported DEP since 2.6.8 (August 2004). Every version of MAC OS X
for Intel chips has supported DEP. Solaris 10 for Intel has DEP enabled by
default. FreeBSD had a DEP option for years, it's enabled by default in the
current release. Windows, Linux, Max OS X, Solaris and FreeBSD make up about
99.99% of the operating system market. They all use DEP.

The problem is not that Vista has DEP enabled; rather, some applications
took programming shortcuts which "looked like a good ideal" at the time, but
are incompatible with secure computing, ie, DEP. Really, you should be
razzing the vendors of your applications, and asking them why they cannot
run in a DEP-enabled environment (and, yes - there are some Microsoft
applications, which have problems running with DEP enabled).

As the other guys have said, you can turn it off it you want. But you're
weakening the security of your system, in the process.

Hope this helps a bit,

Which programs cause you problems with DEP?
I have full DEP in hardware enabled and have yet to find anything that
doesn't work so your list would be useful in knowing what to avoid.
No program should need to write to code space or execute data so DEP
shouldn't cause problems with properly written programs.
I know there were some old programs where the writers though they were
really clever by re-writing code on the fly but that was in the days of 64k
of RAM.

DEP has been around on microprocessors since the Intel 80286.
It had a segmented MMU built in and I thought the idea was really good.
It gave protection to the code and data as it should.
It didn't take off as it went over the heads of most of the programmers of
the day and was killed off in the 80386 in favor of a paged MMU that could
also do DEP but again virtually no programmers used it except for Unix type
OSes and not all off these actually used the protection mechanism.
(Ah the good old days when there were dozens of incompatible flavors of Unix
with different pages sizes, libraries, processor architectures and stuff
like that. The argument that they needed to consolidate into one common Unix
was a favorite one then just as it is today.)
