As many of you may know, cohorts are subsets of Windows systems and devices targeted by a shipping label that share the same attributes (such as HWID, CHID, OS Version, etc.). Earlier this year, we started to analyze drivers not just by the entire shipping label, but also by cohort to better identify quality.
Starting October 30, 2020, if your driver is canceled due to a failing targeting cohort, you will receive a Cohort Failure Repot with the details of those failures. You can find out how to access and understand the Cohort Failure Report, on MS Docs.
