Dell Precision Optimizer components
The four main components of Dell Precision Optimizer are:
• Performance
• Track and Analyze Engine (TA)
• System Maintenance (SM)
• Dell Precision Optimizer Manager CLI (dpoCmd.exe)
Each of these components are implemented as a Windows service that also acts as a COM server. The Dell Precision Optimizer installer
package installs the services along with Dell Precision Optimizer support DLL(s), user interface (UI) components, kernel mode device
driver(s), and so on into the POA Installation folder. Additionally, a taskbar application may be installed and launched whenever the user
logs in. This application notifies the user about various POA events such as update completion and reboot required.
The Dell Precision Optimizer installer package is also responsible for creating a software registry key that is used by the Dell Precision
Optimizer modules. Following are the default paths:
