Hardware drivers are starting to come out using .NET. Two scanner drivers, Kodak and Savin, seen today doing this. The latest ATI video driver may well do so too. The two scanners were working until a month ago or so, and suddenly stopped. I thought perhaps it was a .NET update issue, so I downloaded the latest and installed…and they worked perfectly. This was an IE7 XP box, so Windows updates probably are fine; for non-IE7 boxes, I would have installed all Windows updates first, to be sure of .NET.
