We had complaints, as well as experiencing the problem with our personal track computers, of Windows 7 going to the "blue screen of death" or just locking up when viewing live data. This driver should take care of that issue. We tested it on our computers and it solved all our problems. I believe this driver will support the previous versions of Windows as well.
