Performance Options -> DEP (Data Execution Prevention)
Turn on dep for essential windows programs and services only
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\NoExecuteState
Set LastNoExecuteRadioButtonState to 0x000036bc (decimal 14012)
also you can do it with bcdedit:
There are four options to set the DEP mode with bcdedit:
- Optin:
Enables DEP only for OS components, including the Windows kernel and Windows drivers.
Administrators can enable DEP for selected executable files with the Application Compatibility Toolkit (ACT).
- Optout:
Enables DEP for the OS and all processes, including the Windows kernel and Windows drivers.
However, administrators can disable DEP on selected executable files with the Control Panel System applet.
- AlwaysOn:
Enables DEP for the OS and all processes, including the Windows kernel and Windows drivers.
All attempts to disable DEP are ignored, and all DEP configuration options are disabled.
- AlwaysOff: Disables DEP. Attempts to enable DEP selectively are ignored, and the DEP GUI is disabled.
Samples:
Turn it on: bcdedit.exe /set {current} nx Optin
Turn it off: bcdedit /set nx AlwaysOn
