Measure attributes
Attribute | Value |
---|---|
Audience | Devices targeted by the driver |
Time period | 7-day sliding window |
Measurement criteria | Machine count |
Minimum population | 5,000 Devices |
Passing criteria | <= 10 rollbacks per 10,000 devices that installed the driver |
Measure ID | 33480951 |
Calculation
The measure aggregates telemetry from a 7-day sliding window into the Ratio of Driver Rollbacks/Another Driver Installs per 10,000 devices that installed this driver
Total Devices That Rolled Back Or Installed Another Driver = Count(devices that rolled back or installed another driver within 2 days from the driver installation)
Total Devices = Count(Devices that installed the driver and used it for 2 days)
Final Calculation
Ratio of Driver Rollbacks/Another Driver Installs = Total Devices That Rolled Back Or Installed Another Driver * 10,000 / Total Devices
