Hey everyone, earlier on today I learned something that I had absolutely no knowledge about, after careful review and study of what it is I figured, why not try and create a guide for those other ExDesians who don't have an understanding about this.

First off, the first thing everyone should know is, what is DEP? DEP stands for Data Execution Prevention which is a security check that has been added to Windows XP SP2 and some other Operating Systems. The general basis of this, is to stop malicious software or "code" to access system resources. In doing this it prevents things such as virus' such as back door trojans from accessing system files and enabling the "cracker" into your computer. There are many other reasons why this is beneficial in having, such as it may help prevent Registry hacks and problems from occuring.

After this short description of what it is and what it does, the next question is, so what? Why care about something such as DEP? It's a safeguard right? Yes and No! It may help stop "malicious" items from being installed or used, but it can actually stop unauthorized software from working. It may even be something that you trust!

For example, you just installed an application, for experimental purposes, we'll say its DVD Shrink. You go to run it for the first time, excited that you are going to be able to "back-up" your movie to your computer, just in case something happens to the origional. But when you double click the application, it doesn't load or you receive an error without the app even loading up. This could have been caused by DEP!!!! cray.gif

The next thing you would want to do then of course, is check to see if you even have DEP, and if you do, make sure the program that you of course trust, is allowed! How do you do this? I will tell you! smile3.gif


First, Click Start, click Run, type sysdm.cpl, and then click OK. System Properties will pop up.
Secondly, click on the Advanced tab, and under Performance, click Settings.
Thirdly, click on the Data Execution Prevention tab, and then follow this procedure:

*Note, if Data Execution Prevention doesn't show up here chances are you are DEP free!*

Click Turn on DEP for all programs and services except those I select to select the OptOut policy, and then click Add to add the programs that you do not want to use the DEP feature. (It may already be selected & you may have some programs already in your "allowed" list, but if you don't have the program you want to be allowed guaranteed, click Add, then cruise on over to your program files in your root directory(usually C:/ProgramFiles/) and find the application you want, for me, I want DVD Shrink, so I double click on that, and find the .exe then, click Open. Finally, I click Apply, and Okay twice.

 Ahh!You have just added something into your DEP allowed list :)

An alternative to the System Properties is clicking start, then settings, and clicking Control Panel, when there, if you use Classic Control Panel, you can just double click the system icon. However, if you use the "modern" control panel, you must select Performance & Maintenance, then at the bottom of that window it will have a System Icon.

Hey,man.your Blog is awesome ,will definitely come again soon ,keep it up.
