I posted my views earlier on Nikon software – and I’m now pretty sure that Nikon ViewNX is broken on Windows 7. Below is a link to the native Process Monitor log file – filtered for ViewNX after a complete uninstall and re-install to the latest version of ViewNX 1.5.0 – running on the RTM of Windows 7. ViewNX was still performing an endless loop of I/O and registry requests.

I stopped recording after 1.7 million events (a 182MB log file – compressed to 21MB below).
