Windows assigns a rank to a driver that matches a device. The rank indicates how well the driver matches the device. ... The lower the rank, the better a match the driver is for the device.
The rank of a driver is a composite value that depends on how a driver is signed, the features that are supported by the driver, and the type of match between the device identification strings that are reported by a device and the device identification strings that are specified in the entries of an INF Models section of a driver INF file.

V GPO se pak dá nastavit že se nebere v úvahu kategorie podpisu driveru (WHQL, OEM, MS, stará verze Windows).
