Default Behavior

Diagnostic Policy Service is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Diagnostic Policy Service is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Diagnostic Policy Service fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the DPS service is not running because of the error.

Restore Default Startup Configuration for Diagnostic Policy Service

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_DPS_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The DPS service is using the dps.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
