Vista SP1 Driver Incompatibility Issues Still Unresolved

Four months since Windows Vista SP1 was released to manufacturing, the driver incompatibility issues affecting the implementation of the service pack are still unresolved. Vista SP1 RTM'd on February 4, 2008 along with Windows Server 2008. At that time, Microsoft informed that it was postponing the general availability of the release in order to give hardware developers a chance to adapt a set of problematic drivers which failed to integrate properly with the service pack. As a result, Vista SP1 didn't drop via the Download Center and Windows Update until March 18. But it looks that the extra time Microsoft provided hardware manufacturers to get their drivers playing well with Vista SP1, a source of obvious end user frustration, failed to deliver an actual result.

On June 5, Microsoft explained that Vista SP1 was still not being delivered to some machines running Vista RTM but featuring problematic hardware device drivers. The Redmond company continues not to serve SP1 through Windows Update or Automatic Updates for Vista copies which include a small set of device drivers causing functionality issues following the implementation of the service pack. With a few exceptions, the list is identical to what Microsoft published back in February.

Obviously, since the Redmond giant has put its evangelism wheels in motion, the hardware manufacturers did provide updated versions of the drivers. However, the problematic items were not tweaked to play well with Windows Vista SP1. In this context, the best course of action is to make sure that you have the latest versions of the device drivers available installed prior to deploying Vista SP1 in case the service pack is not delivered through WU or AU.

Here is the list of Vista SP1 problematic drivers as of June 5, 2008. (Please check the hardware vendors official websites for updated versions of the following device drivers tailored to Windows Vista SP1)
