Every month new patches come out for Windows that sometimes require a reboot. Windows 8 and Windows 7 can force a reboot while you are in the middle of working or left your computer idle for a little as five minutes. In Windows 8, Microsoft removed the ability to indefinitely postpone reboots while you were actively using your PC which can result in lost work if your applications running do not have an auto save feature.
