Microsoft Reveals Vista SP1 Driver Installation Failure Rates

One of the common problems when Windows Vista was released was that of missing or non-working drivers. Microsoft massively reworked many of Windows' internal systems and frameworks, meaning lots of drivers broke, with most of them needing major work, and some even needed to be rewritten completely. Apparently, Microsoft didn't communicate this well enough with its hardware partners - or the partners were lazy, who knows - because many devices failed to work with Vista during its early months of being out in the wild. Microsoft is trying to keep this story from repeating itself, saying that everything that works on Vista should work on Windows 7. To gain a little more insight into this problem, Microsoft gave out some very interesting figures regarding driver installation failure rates.

The below figures come from Microsoft's Online Crash Analysis and Customer Experience Improvement Program tools, and show the success/failure rates of driver installations during September 2008, on Windows Vista with Service Pack 1 installed.
