Data Execution Prevention (DEP)

DEP can be turned on for Windows applications but cannot be enabled for all applications, otherwise the telephony server will fail.

Use the command line to check DEP settings: 

wmic OS Get DataExecutionPrevention_SupportPolicy
  1. Returns 0 = OptIn (default).
  2. Returns 1 = OptOut.
  3. Returns 2 = AlwaysOn.
  4. Returns 3 = AlwaysOff.
