Windows' hidden emergency restart forces reboot if system freezes

Windows has a little-known feature called Emergency Restart, available since Windows NT 3.1, that lets users force a reboot when the system becomes unresponsive. Accessed via CTRL + ALT + DEL and a hidden CTRL + power button click, it acts like a digital hard reset. It's a last-resort tool, useful when the physical power button is inaccessible or fails.
