DEP (Data Execution Prevention) is a system-level memory protection feature that comes inbuilt into the Windows operating system starting with Windows XP. This DEP feature is also available in Windows 10. This protection features help to prevent damage to your computer from viruses and other security threats. It also helps protect your computer by monitoring programs to make sure they use system memory safely.

In case any program or service executes codes from the memory in an inappropriate way, DEP closes the program and protects the PC, that is the beauty of DEP (Data Execution Prevention).

If any program attempts to run code from a protected page, the application receives an exception with the status code. Either you can enable DEP for all the processes and servers or you can add exceptions for particular programs and services.
