I really admire using windows vista, I am using it long time ago and my edition is business one.
3 days ago I discovered a bug in it, don't know how they don't put this issue in their consideration, and don't know if is it bug or no. Let me talk clearly.
If you've have low disk space in your system drive and installed some updates using windows update, and go to turn off your machine you'd see that
So, windows would ask you to not unplug the power lmlmlaa, but it doesn't check if an error would occur or now(I imagine that), I tried it myself, windows still on that screen for more than 6 hours saying don't unplug the power, nothing happened everything works. Windows isn't hang although no progress done, so I hope Windows team solve this issue.
