Microsoft on second Tuesday of every month releases new patches (popularly known as “Patch Tuesday“) for Windows, which sometimes needs a system reboot. We have earlier shown ways to shutdown Windows without applying Windows updates. That quick tip was handy if you are in an emergency and you need to shutdown Windows quickly. Although the software giant is trying to make the Windows update process less intrusive but a force reboot occurs . Windows 7, Windows 8 and Windows 8.1 can force a reboot if you left your computer idle for a few minutes. Sometimes the force system restart occurs when you are working and you didn’t notice the restart timer asking if you to postpone automatic system restart. Since, Windows 8 (and 8.1), Microsoft removed the ability to indefinitely postpone reboots. If you are working using your PC then it can result in loss of your work. The tips in this post will help you disable automatic restart on Windows Update and save your important work.
