At work, we are being split into two companies. A week ago, my computer was supposed to be migrated to the new domain. So I followed the directions to the letter, and naturally it failed.
That night, I had a nightmare. That instead of just switching domains, that my laptop automagagically upgraded to Windows 8. Metro interface and all.
Fortunately, when I woke up, I found that I was still running Win 7 Pro. Phew.
