When a driver fails to install correctly, the targeted component can lose functionality and prevent the user from accessing the component's features. The user must troubleshoot the issue to regain functionality. A list of PNP error codes is located on Device Manager Problem Codes and on Windows Support.

Calculation
- The measure aggregates telemetry from a 30-day sliding window into a Percentage of Machines that have Successfully Installed the Driver.
- Successful Installs= Count(machines with successful PNP events)
- Total Installs= Count(machines that started the driver install process)
Final Calculation
PNP Success Rate= Successful Installs / Total Installs
