Disable DEP

DEP (Data Execution Prevention) is a new feature that was introduced with Windows XP SP2 and above, to prevent running of malicious codes, it marks certain memory locations as non-executable. But sometimes it creates problem with applications that are not doing anything harmful and they crashes. In XP SP3 and above Microsoft introduced new APIs that allow us to disable or enable DEP on our applications. This code shows how you can disable or enable DEP at runtime for your applications.
