Windows 10 has a secret reboot mode called "Emergency restart". When you perform an emergency restart, Windows closes all running apps forcefully and you will not see any warning about saving your work. This way of restart can be useful if you have some issues with apps or the OS hanging or crashing and you would like to quickly restart the PC to fix it. Follow this tutorial to learn how to perform an emergency restart in Windows 10.
