It’s pretty hard to figure out how to reboot or shutdown Windows 8 only use mouse/keyboard. After a few hours search in Google, here comes all options I found. All of them work but involved too many steps. It sucks there is no one click shutdown shortcut.
- Hover the mouse over the lower right corner ( or WinKey + C), in the right menu, Settings –> Power –> Sleep/Shutdown/Restart.
- In desktop mode, press Alt + F4.
- In user switch screen, highlight username, sign out and then shutdown.
- Running shutdown in cmd.
- Shutdown: shutdown /s
- Restart: shutdown /r
Feel free to comment if you found other options
