What prevents data processing in Windows 10?.

Data Execution Prevention (DEP) is a system-level security feature included in Windows machines. The main purpose of DEP is to control processes and services to protect against exploits of malicious code by closing any program that is not working properly in memory.

Also known as executable space protection. This feature includes a set of hardware and software technologies that perform additional checks on system memory to prevent malicious code from running.

When malware tries to execute code in certain areas of system memory reserved for authorized programs and Windows, DEP marks them as non-executable and throws an error.

All of this is done to prevent viruses and other security threats from damaging your computer. However, DEP can sometimes interfere with legitimate programs such as your antivirus, in which case you may have to disable this feature for certain applications.

How Data Execution Prevention in Windows 10 Works

DEP is not comprehensive protection against all malicious code exploits; it is just another tool that can be used in conjunction with security software for your applications.

Many operating systems have reserved areas of memory in which important programs and functions run.

When this happens, it can provide access to potentially sensitive data to users or programs that should not have access to it.

DEP intervenes to resist such access or execution of any executable programs that are not allowed to load in the system memory area. This function immediately throws an exception when it detects a download of suspicious code and prevents it from running.

The downside to DEP is that it can flag old third-party programs that rely on Windows services. However, you can disable DEP or create an exception in your system settings to enable such programs to run.

Note. Some DEP errors are caused by outdated device drivers on the system.

Types of Data Execution Prevention in Windows 10

There are two different methods for creating a DEP:

• Hardware DEP
• Software DEP

Hardware DEP

Hardware DEP detects suspicious code that runs from memory areas as non-executable, intercepts and throws an exception to prevent any attacks on the system. The only exception is the region that specifically contains the executable code.

Hardware DEP relies on processor hardware to tag memory with an appropriate set of attributes indicating that code should not be executed from that memory.

To use hardware DEP, the following conditions must be met:

• Your computer’s processor must support hardware DEP support. The actual hardware implementation of DEP depends on the processor architecture, such as AMD and Intel, whose Windows-compatible architectures are also DEP-compatible.
• Enable hardware DEP in BIOS.
• Your computer must be running Windows Server 2003 with Service Pack 1 or Windows XP with Service Pack 2.
• Enable hardware DEP for the programs on your computer. In 32-bit software, hardware DEP may be disabled depending on your configuration, but on 64-bit versions of Windows, this option is always enabled for 64-bit firmware.

Not sure which version of Windows is installed on your computer? Here are four ways to find out if you are using 32-bit or 64-bit Windows.

Programmatic DEP

Programmatic DEP is an optional set of DEP security checks that help prevent malicious code from using the exception handling mechanisms in Windows.

This type of DEP runs on any processor that supports Windows XP Service Pack 2 and only protects limited system binaries, regardless of your processor’s hardware DEP capabilities.

How to Know if DEP Is Active on Your Windows 10 PC

You can check the DEP status on your PC system by following these steps:

1. Open Control Panel and select “System and Security”.

1. Then select System.

1. Enter “View Advanced System Settings” in the search box.

1. In the System Preferences pop-up window, select Preferences under Performance.

1. Select the Data Execution Prevention tab to open the DEP settings.

1. You will see your current DEP status on your system and whether your computer’s processor supports hardware DEP.

1. You can also add exceptions to DEP if needed but do so only if there are no other alternatives. To add exceptions, select Turn on DEP for all programs and services except the ones. I have selected and then click Add. Select the executable file you want to exclude, and then restart your computer for the changes to take effect.

How to Enable or Disable DEP in Windows 10

You can disable DEP in Windows 10 to make certain exceptions or modifications for some applications that will be used in Windows 10.

1. To get started, select Start and type CMD to open the Command Prompt menu. Select “Run as administrator” to open an elevated command prompt.

1. In the Command Prompt window, enter the following command: BCDEDIT / SET {CURRENT} NX ALWAYSOFF and press Enter. The change will take effect after you restart your computer. In some cases, you may need to change your BIOS settings to disable DEP using this command.

Note. If you want to disable DEP for a program you trust, first check to see if the publisher has a DEP-compliant version or updates are available. If a DEP-compliant version or update is available, install it and leave DEP active so you can enjoy the protection it can provide. Otherwise, disabling DEP could leave your system vulnerable to an attack that could spread to other files and programs.

1. To re-enable DEP, open an elevated command prompt and enter the following command: BCDEDIT / SET {CURRENT} NX ALWAYS. Restart your computer for the changes to take effect.

Enjoy DEP Protection

While Data Execution Prevention is an important feature, not all software and hardware fully support it. For this reason, your computer may experience certain problems and error messages due to conflicts that some Windows processes encounter when working with DEP.

However, DEP is one of the simplest Windows-based system protections. Unless there is a compelling reason to disable it, DEP should always remain active by default and should be treated with caution.
