Preparing Windows Servers for the Upgrade › Configure DEP

Configure DEP

Data Execution Prevention (DEP) helps to prevent code executing from data pages. We recommend that you configure the DEP policy as described in this topic.

Follow these steps:

1. Log in to the server as an administrator.
2. Open the Advanced tab of the System Properties dialog. For example:
   1. Select Start and right-click Computer.
   2. Select Properties from the menu.

      The System window opens.

   3. Click "Advanced system settings" on the left.

      The System Properties dialog opens with the Advanced tab displayed.

3. Click Settings in the Performance section.

   The Performance Options dialog opens.

4. Click the Data Execution Prevention tab.
5. Select "Turn on DEP for essential Windows programs and services only."
6. Save your settings and exit:
   1. Click OK in the Performance Options dialog.

      Your settings are saved and the dialog closes.

   2. Click OK in the System Properties dialog.
7. A message opens and informs you that you must restart your system to make the new settings take effect.
8. (Optional) Restart your system before you install or upgrade the software.

   If you proceed with software installation or upgrade without restarting the system, the prerequisite test displays a warning about your DEP configuration
