The new R2 release of Windows Server 2012 makes it just a little trickier to power-down a server. Here are the steps with screen-shots showing how it’s done.
First click on the Windows image in the bottom left-hand corner of the screen:
You then seen the new “start” screen:
What isn’t obvious at this point is that if you now move your mouse, some icons show up along the right side of the screen, AND a little minus-sign shows up in the bottom right-hand corner of the screen:
DON’T click the minus sign because that will just shrink the screen tiles. Hover above it then move your mouse up to the Settings icon (looks like a gear):
That Settings icon brings up more options, one of which is Power. Clicking on Power then gives you the option to Shut down the server or Restart it.
I hope this saves you all the time I spent clicking everything in sight looking for an option to power down my machine. :)
