Could you rephrase the question?
Data Execution Prevention addresses an inherent shortcoming in the architecture of most modern microprocessors - that they will treat data like program memory, and may try to "execute" it. This shortcoming is sometimes deliberately exploited by malware, but also happens with badly written software (which you probably don't want on your machine anyway). So, DEP protects against some types of malware, and protects against some types of crashes caused by badly written software. By default DEP is enabled for all the Vista operating system files. You would be advised to enable it for all programs, although some simply won't run with DEP enabled (Omnipage Pro 15 is an example on my computer). In that case, you can add the troublesome executables to the exceptions list. I'm not sure if this addresses your question. If not, perhaps you could express it more clearly? SteveT |

SteveT I'm afraid you're wrong, Steve. When I checked my Vista Home Premium, I found that it was disabled. And a little research uncovered that by default settings at least in this version, are disabled. |

I'm afraid you're wrong, Steve. When I checked my Vista Home Premium, I
found that it was disabled. And a little research uncovered that by default settings at least in this version, are disabled. That's funny, I could have sworn that my pristine Vista installation had DEP enabled for the core Windows files. In fact, I've just checked the Windows Help and Support page, and it implies the same thing: "DEP automatically monitors essential Windows programs and services. You can increase your protection by having DEP monitor all programs." Anyway, the rest of what I wrote was correct: DEP is a GOOD THING, and if a program gets caught by DEP then it is badly written and a potential security hazard. Of course, sometimes you've no choice but to run it anyway, but having been in the electronics and computing field for over 30 years I strongly suggest that you enable DEP for everything, and then switch it off on an application-by-application basis if you find you have to.

In fact, I think it's you that's wrong, hermit.
I've just looked at the DEP settings on my PC (Vista Home Premium), and it appears not to be possible to switch DEP off altogether. The top radio button says "Turn on DEP for essential Windows programs and services only". I don't know where you did your research, but did you actually look at the settings box in your own machine? I can't believe it's different from mine. SteveT |

Steve apparently your system hardware supports DEP as shown on the bottom of
the DEP screen And it is possible that hermit's does not which means he would get a different dialog screen. "Steve Thackery" wrote in message ... In fact, I think it's you that's wrong, hermit.

I could have been clearer, so I'll restate: Under Internet Options Advanced tab in the Security section there is an option to check a box marked 'Enable memory protection to help mitigate online attacks.' This is greyed out & I can't check to enable it, even though I've right clicked to 'Run as Admin.' Been told to right click on IE7 exe. but can't find it. When I right click on Internet Explorer, I am redirected / connected to 'hp-desktop.aol.com.' This is one of two DEP locations & is not checked in my OS. Can you help me get this section turned on, or does it really matter??? 2) The second location where there are two options, I can change. However, when I made the change to 'Turn on DEP for all or all programs & services except those I select,' I get an Error Msg that server can't be found when using IE or Firefox regardless how many refresh attempts. So I've gone back to the original setting. I'm concerned that in that setting my comp. isn't as secure as it could be, but it seems I have no choice. I hope this clears up my vagueness. |

......there is an option to check a box marked 'Enable memory protection to help mitigate online attacks.' This is greyed out & I can't check to enable it, even though I've right clicked to 'Run as Admin.' Hey, that's fascinating. I've never noticed it before, and it is greyed out on my machine, too. The Help for it is useless, so I don't know whether this is another "button" for switching DEP on and off, or something else. The second location where there are two options, I can change. However, when I made the change to 'Turn on DEP for all or all programs & services except those I select,' I get an Error Msg that server can't be found when using IE or Firefox regardless how many refresh attempts. That's strange, because both work fine on my machine, with DEP switched on for everything. I wonder if you've got any plug-ins for the browsers. They can definitely cause this kind of problem. If you can isolate it to a plug-in, I'd disable it and inform the author. It occurs to me that you could, for now, simply add IE and Firefox to the "Except..." list. Sorry I can't be of more help. Perhaps someone who knows more about it might join in.... SteveT |
