Ironic, isn’t it?
It’s been a while since Windows has blue-screened on me. Probably a couple of years actually. The other day I got a blue screen for the first time on my Vaio. When the restart was complete, I was greeted with this priceless gem…

I love that Windows protects me from Microsoft processes…
Of course, you realize that the process in question houses dozens of services. Although the odds would say it was a MS service, this process is just a wrapper, so don’t shoot the messenger.
LOL! ;-)
In my 2.5+ years w/ a Mac iBook, OS X has never crashed on me. Individual apps have, but not the OS.
