Should you be concerned about this? Surprisingly the answer is “Yes,” even if your systems aren’t experiencing the problems this update is supposed to address. As it happens, many storage devices–including SSDs, USB flash drives, network storage devices, and even conventional SATA or IDE hard disks–actually include Plug and Play SCSI Miniport drivers among their Host Bus Adapter capabilities. This could be one of those surprising updates that might (or might not) cause heartburn on end-user machines. A little time with this puppy in the test lab on standard configurations is probably in order. So far, all of my test machines appear to be working OK in the wake of the update, but you can’t know about yours until you try it out in the lab.
