At least once a month on my PC, Vista will reboot without warning!
No dialog box, no warning box, just all of a sudden everything begins to shut down and then Vista reboots. A search on Google and Microsoft's site has turned up nothing that discusses or addresses this behavior.
I could attribute this behavior to Windows Update which as a rule updates on Tuesdays, but today is Saturday, it is 8 in the morning and once again Vista did an auto reboot.
Even stranger is that I had been working on the PC for at least 30 minutes.
Well once again this just serves as an example of the lack of thoughtful design and professional programming practices that should have been in Vista, especially after 7 years of development.
