DEP

How can Data Execution Prevention be removed completelu of a computer system?

Hi im4jezus,

Thank you for taking the time to post on the Microsoft answers Forums.

The research we did we do not see DEP can be deleted, but it can be disabled. Please see below for how to turn off DEP.

Deactivation of Data Execution Prevention (DEP)

Data execution prevention is a security feature that can be a bit of a pain at times. Often things just seems to not work at all; I hope that you will notice a bubble in the taskbar letting you know that the EPD is the cause. If Vista sees that a process is being generated which "could" be unwanted, DEP it stops. It is particularly common in some app installs: If an installation of Windows Installer (MSI) call an executable file in Vista, DEP might very well put an end to it. If you try to run a facility, or any other executable by DEP, it could save some difficulties then you stop while you try to give it another shot.

Run a command as administrator prompt. On the start menu, select "All programs", then "Accessories" and right-click on the "Command prompt" shortcut and choose "run as Administrator". From here, you can use the following command to turn off the Data Execution Prevention (DEP) with the following command:

bcdedit.exe/set {current} nx AlwaysOff

Maintain your open command prompt, run your installer or other processes being interrupted by the DEP. Then, to turn back on again, do the same thing and run the following:

bcdedit.exe/set {current} nx AlwaysOn

Please post back and let us know if this information has helped to solve your problem or not, so that we can help you if necessary.

  • We need DEP in China and Korea

    We are a global company with DEP in most countries but not in China and Korea, I think that local regulations prevent us to do so. We have a problem because we are unable to track our assets in the country that gives us a headache of checking. Is there a way to get around this or an alternative in these countries?

    I would like assistance in this case.

  • Portege M700: Message DEP, saying he has turned off the Tablet PC Component

    Windows Vista Business SP1 is intermittently during starts with a message DEP saying it has disabled the "Tablet PC Component". Unexpectedly, this happened 5 times in the last 3 days. Once it happens, data via the touchpen entry and writing entry tool no longer works correctly.

    I reported this to the Toshiba UK support and they told me to restore the system from the recovery - disk

    Are you serious? It's what - after I spent almost 4 hours updating the BIOS, Windows Vista SP1 and MS Office then set up Outlook for Exchange server and HSDPA too?

    Looks like there is only not all tested against Vista and Office upgrades...

    Should I turn off DEP?

    Hello

    You can still leave the active DEP but could add the Tablet PC Component (touchpen) to the list of applications that are ignored by the DEP.

    You could do this in:
    Control Panel-> system-> system settings-> advanced-> first button settings tab advanced-> last tab Data Execution Prevention (DEP)

    Here, you can choose the second option and could ad the touchpen (exe) to the list

  • DEP errors & host Generic Service on WinXP Home Edition PC

    OK, I have Windows XP Home Edition with Service Pack 3. Since SP3 has been installed or later, I get the error messages nagging from DEP regarding Generic Service host (Win32).

    It happens that when I start my PC, then once in a while during the operation of my computer; I get a svchost.exe error. "svchost.exe... instruction at '0x010906d1'... '0 x 0000001' memory reference.»

    What I can do to fix this problem or do I remove SP3?

    Not a good thing... .removing any SP... and I don't think that the deactivation of the DEP is a good idea either.

    Can someone help me really?
