Machines that reported a Plug and Play (PnP) error code within two days of installing a driver update

Description

Machines can experience post-installation Plug and Play (PnP) errors that result in a negative user experience; from the device not working as expected to an unexpected reboot. A list of PnP error codes is located on Device Manager Problem Codes and Error codes in Device Manager in Windows.

Calculation

  1. The measure aggregates data from a 30-day sliding window into a percentage of machines that successfully installed the driver, then encountered a PnP error within two days of installation

    1. Any PnP errors associated with an install outside of the 30-day window aren't counted
  2. Post installation PnP errors = Count(machines with a PnP error,within two days of driver installation)

  3. Total post installation errors = Count(all machines that successfully installed the driver)

Final calculation

Post installation PnP error rate = post installation PnP errors / total post installation errors
