Windows 7: unable to use DEP to accept games (cant add games in the aproved list)

first off, sorry about my bad english, i am from holland (where education needs inprovement if you ask me)

anyway, i resently had my laptop reinstald from vista to windows 7 (my C was full and i had nothing instald on it, its just up-dates, so it was needed)

the problem now is, before if some games dont work as the sims 3, i just opend the system en opend the advanged to add the sims in a list that DEP allows it and problem solved.

but for some reason i cannot do that now, the text below command about needing to be admin (wich as only user on the lap i am), and run the BCSEDIT.exe.
i run it (even as admin) but it the problem keeps going on.
i noticed some ways to turn the DEP off on this site, but that seems a bit extreem (as that people most of the time warn that its not the best option)
i just want to get the old system of having it on but beeing able to allow games by adding it to the approved list.

somebody knows how?

I've never heard of anything like this even being necessary...

Did you enable DEP "for essential Windows programs and services only"? IMHO, that's the only setting you need.

that is kinda the problem, those options are.., how to put it..., there in gray while they supposed to be black (including the add and remove) there unclickable and nothing is selected to start with

not the one you mentoined, and not the one below it
its been this way sinds i got my laptop back, and i cannot find out why and how to fix

Let me see if I understand this right. Both radio buttons (DEP for Windows only/DEP for everything) are unchecked, and you can't check either one? That's pretty weird.

Even if your CPU doesn't support the no-execute bit, Windows should still offer software-based DEP for its own processes.

At the bottom of the window, does it say "Your CPU supports hardware-based DEP"?

the window of the dep?

no, just to use this i need to be the admin (as only user i am) and run BCDedit, but using it as its say's makes no diffrence

This is starting to make less and less sense. Where does it tell you to run bcdedit and why? And what's this got to do with DEP?

right below the (gray out) buttons of add and remove

going to translate it:
"if you want to use this instalation, than you have to be a admin of this computer and use the file bcdedit.exe.
for more information contact microsoft"

I'm sorry but I'm lost here. Never heard of this in connection with the DEP settings before. Could you take a screenshot and upload it here?

ok, but its in dutch so you will problable need a translator, unless the pic explains it...




and if in case its not view able (as right now, but cant seem to fix that)

Ahhhhhh....of course, now I get it.

DEP requires a setting named PAE to be enabled, which means Physical Address Extension. Windows should automatically enable PAE during installation if your CPU supports hardware-based DEP and/or you have more than 4GB of RAM.
For some reason PAE must be disabled on your system. And the PAE setting is stored in the BCD...that's why Windows displays the message about bcdedit.

To enable PAE, open a command prompt with administrative privileges and type the following:
Then simply reboot your computer and try the DEP setting again.

(I still think you only need to enable DEP for Windows services etc., not for all programs on your computer. That way you don't have to add any exclusions to the list - but of course you can, if you prefer.)

Let me know if this works for you.
