Device drivers Rating, punish vendors

Microsoft (Quote) is putting its Windows Crash Analysis reports to use in a way that is sure to give new meaning to the term making the grade.

The company is launching a Driver Quality Rating (DQR) system that will grade device drivers on their quality, based on how often they crash. A low grade could mean OEMs will shun the product.

The DQR system scores driver on a 1-9 scale, with one being best and nine the worst. Drivers that rarely, if ever, crash will be scored 1-3 and rated "green."

Drivers with a modest record will be in the 4-6 range and rated "yellow."

The kiss of death is a 7-9 score and a "red" rating. The score will be generated from user-submitted crash reports.

The Online Crash Analysis Team will be a part of the Windows Hardware Quality Labs (WHQL) program. WHQL will handle crash submissions and testing drivers. Also, driver manufacturers will be given a test suite that Microsoft uses internally to certify their drivers, according to Raghu Ram, group manager for the Windows logo program.

To achieve a "Green" status, a driver must have been released and in use for at least 120 days, starting June 1, 2007, and must maintain that stability for the 120 days. If the driver suffers problems and loses its Green rating, the OEM must resolve the issues within 90 days.

Failure to do so would mean losing the right to claim a Windows Premium driver status, said Ram. It's hardly punitive but it is a loss of bragging rights. Microsoft is doing this to light a fire under some hardware providers to offer better quality device drivers, since they are often the source of system failures.
