If you want to check your system and see what is DEP-enabled, you can open up Task Manager,
go to the Details tab (the View menu in Windows 7), right-click the column headers, and use the Select Columns feature to add the Data Execution Prevention column. On our test system, every process that we used had DEP enabled, including the 32-bit version of Chrome that was running.
Note: The configure button applies to the disk selected in the Protection Settings area. This allows you to disable System Restore for a specific partition (such as the factory recovery partition) or for a separate data disk, if so desired.
