My Labtop was still showing me 'shout down' without doing anything.

Hi everyone!

While installing updates of windows, I was told that I shouldn't have turned off my computer. However, I had to turn it off because I saw that while installation of updates is about 32%, and in the 3/3 stage, that my computer was still 'shout down' without proceeding restarting my compute to finish the updates.
I had to shout down it by clicking on the turn off' button in the keyboard because it took too long time without doing anything.
Although I have been told to not turn off my computer or plug off until the updates are installed, I had to turn off it.
So my questions are:
Why did this happen(my compute was still showing me 'shout down' without doing anything.
Why were the updates completed, although I have been told to not turn off the computer while updating installing. But I didn't do?
Finally: why is not there restart' button on the keyboard to restart the compute if necessary.

Just wait until the PC reboots and the Updates complete. If it takes more than a few hours then you can shut it down, if necessary run System Restore from System Recovery Options

Thank you so much indeed, but
I saw that the updates was completed after turning on my computer again, although I shout down my computer by clicking on 'shout down' button on the keyboard.

Finally: why is not there a 'restart' button on the keyboard to restart the compute if necessary because sometime the laptop is frozen.
