Edit - Nevermind, blue screens are listed in a separate section below. So I'm going to conclude that these are application-level crashes.
BTW without knowing what is "Based on Soluto community data" we can't really judge if their analysis has any sense.
Personally, I'm ill informed with most "software" languages and mostly use web languages and some c++ in my spare time projects, but this gave me quite in depth knowledge without getting overly technical.
I would definitely recommend a read to everyone scrolling past this comment.
I haven't really looked into the issue much because it isn't a showstopper but I suspect the problem has to do with thumbnail generation because I mostly see it when navigating folders full of video clips used for video editing. It is possible/probable that explorer itself isn't what is crashing but rather some dependent codec used for the thumbnailing is crashing, but it would be nice if explorer isolated itself better from such crashes.
It's interesting that windows explorer under windows 8 is crashing that much. I guess there's a lot of new code in it.
Whenever I shutdown/restart Windows 8 for my monthly update (or whenever my machine gets too slow), most of my applications crash out (meaning, they can't shutdown in time for Windows to complain about it and ask you to crash the apps explicitly). This is with decent network.
Windows Server 2012 is a whole other story for me though.
