Sometimes Windows 10 updates are pending but either:

 - I need to shut down or reboot quickly
 - The computer is acting funny and that's why I need to reboot (yeah, it's still Windows), and I don't trust running updates at that time.  No point in making a bad problem worse.

However, this does not seem to be an option the power menu:

  - Sleep
  - Update and shut down
  - Update and restart
