How to disable Data Execution Prevention (DEP) in Windows 7 and above

Problem:
Sometimes, VuGen will not record any events while recording the AUT. If you raise a HP ticket for this problem, HP team will ask you to check your DEP settings is disabled.
Now we see how to disable the DEP settings in Windows 7 and above machines.

Steps:
1. Login to Windows with a user account that has administrative privileges.
2. From a DOS command line run the command "> bcdedit.exe"
Confirm the default value for the "nx" parameter. If it is OptIn, then DEP is enabled.

3. Disable DEP by setting the "nx" parameter to "AlwaysOff" using the command "> bcdedit.exe /set nx AlwaysOff"

4. Rerun the command in step 2 above and verify that the "nx" parameter is set to "AlwaysOff".

5. Reboot the system to ensure that the "nx" parameter setting takes effect and DEP is disabled.
