As I said earlier, the Engadget post has instructions for changing this icon, which gave me the idea to replace it with the
sudo mv public.generic-pc.icns public.generic-pc-old.icns
[enter your admin password]
sudo cp ~/Downloads/vista.icns public.generic-pc.icns
This will make a backup of the BSOD icon, and replace it with the Vista icon. If you downloaded the Vista icon somewhere else, just replace ~/Downloads with whatever location you saved it in. You might not see it right away, so you'll need to relaunch Finder or reboot.
So, hopefully Microsoft will appreciate that I am trying to give them a better name on the Mac side of things and won't send me a takedown notice. If I make a better one, I'll post it up here.
