In this user guide, we are going to identify some possible causes that might cause regedit dep to be disabled, and then I will suggest several possible recovery methods that you can try to fix this problem.

It describes in simple terms how Data Execution Prevention (DEP) works and how to turn it on and off in Windows 7, Windows Vista, Windows Server 2008 (R2).
Data Execution Prevention (DEP) is a processor safety feature that prevents an application from executing code from a non-executable region of memory. This is to prevent a successful buffer overflow intrusion. Since Microsoft introduced the preventionData Execution Protection (DEP) for Windows XP SP2 and Windows Server ’03 SP1 is included as a reference for every version of Windows.
How DEP Is Done: Hardware Implementation And The Role Of Operating Systems ^
How do I turn off DEP in settings?
Under Tasks, select Advanced System Settings. In the System Properties window, under the Advanced Monthly Payments tab, under Performance, select Settings. In the Performance Options window, select the DEP tab. Make sure DEP options are grayed out.
DEP works by observing that some pages of memory are indented so that they only execute data, not executable code. This is achieved by setting a special small number of its entry in the page table named NX for No eXecute or XD to disable delivery. Your operating system is responsible for setting the NX bit in the stack and heap memory areas. If bad software — or spyware — tries to run code from a single memory marked with NX on the page, the processor will reject it and instead cause an effect that causes the operating system to abort the page’s application accordingly.
Enabling And Disabling DEP Support Control On The Panel ^
DEP can not only prevent the use of malware or broken applications, but also identify problems with outdated software.(incompatible with DEP) that can lead to a crash. Another potential problem is serving third-party plug-ins, such as those found in browsers or Office applications: while the application itself may be DEP-compliant, it is highly likely that one or more specific plug-ins will not be. Microsoft recommends updating your software if it crashes due to DEP, but this is not always possible. For different situations, DEP support in Windows can be designed to meet user needs and exception handling for some software.
Should I turn DEP off?
Disabling DEP is not recommended. DEP automatically monitors critical Windows programs and service providers. You can level upprotection by developing DEP Monitor All Programs. First, check for cases where a DEP-compatible version of a program should be available by visiting the software manufacturer’s online store.
However, there are some limitations when disabling or enabling DEP support. Since dep is supported by a kernel-mode parameter, it must be created as a boot parameter. Therefore, it is not always possible to centrally manage and deliver DEP settings using Group Policy; each must be configured on a local server and requires the Windows computer to take effect. Settings
Access to the graphical interface floorThe user can be obtained as follows: open the control panel, select “System and security” → “System” → “Advanced system settings”. On the Advanced tab, click the Settings link under the Performance section (the first is amazing). In the performance parameters, Data Execution Prevention has a separate tab. Here you can disable all electronics in the support only for the main Windows channels and services (OptIn, standard for Windows 7 workstation) or for all programs using the option to set exceptions for incompatible software (OptOut, Standard for Windows Server 2008/2008 R2 ). This can be done using the Add button, where the local administrator can also simply add incompatible executables individually.
Exceptions can also be configured as a DisableNX compatibility fix using the Application Compatibility Toolkit (ACT). The resulting custom compatibility index can be made available in Active Directory. Please note that exception types are not always displayed in the settings GUI support for DEP.

De And Enable DEP Support As A Boot Option ^
At the end there are two more DEP settings for a large Windows computer. These options cannot be configured in real time in the control panel, but only as a useful boot option via the bcdedit list on the command line with multiply privileges / set
current bcdedit nx AlwaysOn
In this mode, the DEP support options graphical interface is usually disabled and no exceptions can be set. All DisableNX compatibility options are also ignored.
bcdedit / set current nx AlwaysOff
If this parameter affects the GUI support for the DEP parameter, an attempt is made to disable it as a boot parameter. To return to one of the GUI toggle modes, use:
bcdedit / set current nx OptIn
How do I disable DEP in BIOS?
Open the control panel.Go to the “System” and “Security” and “System” section.From my left menu select Advanced System Settings.Select the DEP tab.
for a workstation standard that allows DEP support for core Windows programs and installations, or:
bcdedit / set current nx OptOut
for a site standard that allows DEP support for all exe files. Computer with Windows must be rebooted each time for bcdedit to take effect. Place an order:
Is there a way to turn off DEP?
Your computer chip supports hardware DEP, which means that every 64-bit process is always protected. The only way to prevent DEP from protecting a 64-bit application is to completely reset it. You cannot manually disable DEP for this, so you must use the required line.
bcdedit / enum
