Dep in windows explorer

Disallowing write access ensures maximum protection for executable regions of process address space. You should attempt to create applications that use the smallest executable address space possible, which minimizes the amount of memory that is exposed to memory exploitation. You should also attempt to control the layout of your application's virtual memory and create executable regions.

These executable regions should be located in a lower memory space than non-executable regions. By locating executable regions below non-executable regions, you can help prevent a buffer overflow from overflowing into the executable area of memory. Some application functionality is incompatible with DEP. Applications that perform dynamic code generation such as Just-In-Time code generation and do not explicitly mark generated code with execute permission may have compatibility issues on computers that are using DEP.

Most applications that perform actions incompatible with DEP must be updated to function properly. A small number of executable files and libraries may contain executable code in the data section of an image file. It is one of those Windows features that does actually provide value for users.

With more viruses and malware than ever floating around the internet, any extra layer of protection is a good thing.

If it gives the odd error now and again, that is a small price to pay. Some violation errors are nothing to do with Data Execution Prevention at all. It is sometimes, but not always. You can also experiment by disabling UAC, temporarily pausing your security software or by running the program with Admin privileges.

This article also describes how to confirm that hardware DEP is working in Windows. Many recent processors support hardware-enforced DEP. This processor support may be known as NX no-execute or XD execute disable technology. To determine whether your computer's processor supports hardware-enforced DEP, contact the manufacturer of your computer. This support can't be disabled. Both bit versions and bit versions of Windows support hardware-enforced DEP. In bit versions of Windows, hardware-enforced DEP is always enabled for bit native programs.

However, depending on your configuration, hardware-enforced DEP may be disabled for bit programs. DEP can monitor your program to ensure that it uses system memory safely, thereby helping to protect your computer.

If DEP finds that a program on the computer is using memory incorrectly, it will close the program and notify you. After learning about "what is DEP", let's see how it works. If your application must be run the code from the memory page, it must allocate and set appropriate virtual memory protection attributes.

Heap allocation by calling malloc and HeapAlloc functions is not executable. According to the non-execution page protection policy setting in the startup configuration data, DEP is configured at system startup. If you want to turn off DEP for a program you trust, first, check whether the software publisher has made a DEP-compatible version of the program or made an available update before changing any DEP settings. If there is an update or DEP compatible version available, we recommend installing it and leaving DEP on so that you can benefit from the protection it provides.
