Power/shutdown button may be missing from the Windows 8.1 start screen

Summary
After you install or upgrade to Windows 8.1, the power/shutdown button may not be present on the start screen, depending on the kind of hardware that you have.
More information
The following table summarizes when the power/shutdown button should be present on the start screen after you install the Windows 8.1 update:
Device typeSupports Connected StandbyScreen sizeShow power/shutdown button by defaultDefault behavior is customizable by the manufacturer
SlateYes<8.5"NoNo
SlateNo<8.5"NoYes
SlateYes>=8.5"NoYes
SlateNo >=8.5"YesYes
All other devicesDoesn't matterAll sizesYesYes

Note An entry of "Slate" in the Device type column means that the hardware reported a Power_Platform_Role of PlatformRoleSlate. To determine what a system is reporting, run the powercfg /energy command, and then notice what is listed for Platform Role in the output.

Example Microsoft Surface behavior for new installations is as follows:
  • Surface RT or Surface 2: No power button on start screen
  • Surface 3: No power button on start screen
  • Surface Pro or Surface Pro 2: Power button on start screen
  • Surface Pro 3: No power button on start screen
Note The images that ship with the Surface 3 and Surface Pro 3 are configured to show the power button. This is a customization that is included with the image.

To change the default behavior when Windows images are being deployed, IT professionals should set the Microsoft-Windows-Shell-Setup | ShowPowerButtonOnStartScreen Unattend.xml setting for new installations.
