> Fundamentally, what advantage is Windows going to maintain with a closed source kernel? Just to hammer this point home some more: There are actually also significant disadvantages to the Kernel being closed source. As an example: Windows has had an official port of OpenDTrace for a year now. But sadly, the documentation for it is almost nonexistent, and just finding out which functions you might want to instrument (and what context data is available there) is much more painful than on other systems. OTOH, if you're on OpenSolaris or Linux (where you'll likely use bpftrace instead), documentation on the matter is abundant.
