Data Execution Prevention will not let me turn off for nothing

Data Execution Prevention (DEP) blocked one of my games to open. I followed the steps to turn it off, but when I get to the window with the option "Turn on DEP for all programs and services except those I select", it is grayed out and won't let me select it. I am the administrator (my account is the only one on this computer), so I don't know why it doesn't let me do. I have looked everywhere and can not find someone else with the same problem. I have Vista Home Premium, 64-bit, if that helps at all.

Hello

First of all, I suggest you to see if a Data Execution Prevention of the game compatible version is available by visiting the website of the software publisher. If the Publisher has not released an updated, compatible version DEP for the program, you can turn off DEP for the program that was closed. You will be able to use the game, but it might be vulnerable to an attack that could spread to your other files and game.

I would suggest trying the following steps and check if it helps.

Step 1: Open the elevated command prompt, follow the steps to open the elevated command prompt.

a. click the Start button.

(b) in the Start Menu, click programs principally made, followed by accessories.

(c) in the menu accessories, right-click on command line option.

d. in the drop-down menu that appears, click on the "Run as Administrator" option.

e. If you have the User Account Control (UAC) enabled, you will be asked for permission before the opening of the command line. You simply press the button continue if you are the administrator or insert password etc.

Step 2: Try the following steps to activate the Data Execution Prevention, using commands.

a. in the elevated command prompt, type bcdedit.exe/set {current} nx OptIn and press enter.
NOTE: If for some reason that this command does not DEP after restarting the computer, then use the command bcdedit.exe/set {current} nx AlwaysOn rather.

b. you should get a success return message.

c. close the elevated command prompt.

d. restart the computer to apply.

Note: Once you are done with step 1 and step 2, try to add the data execution prevention program and check if it helps to open the game or not.

Hope the information is useful.

    Hi, Tractor1o1,

    If you choose to protect all programs, you can always turn off DEP for individual programs. If you think that a program does not run correctly when DEP is enabled, check for a compatible version of the DEP program or an update from the software publisher before you change your DEP settings.

    Hello

    Usually the laptop should start over without any big delays
    But if the laptop was arrested then you must wait 10-20 sec has only the HARD disk, and then you could feed back to the top

    I have no explanation why it takes 5-10 min in order to restart the laptop but it is definitely not normal.

    But it s also strange that this problem does not appear still, but only sometimes and I think it will be very difficult to reproduce this problem
    However, if you want you can contact ASP (authorized service provider) in your country one could ask hardware checks
