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 type Supports Connected Standby Screen size Show power/shutdown button by default Default behavior is customizable by the manufacturer
Slate Yes <8.5" No No
Slate No <8.5" No Yes
Slate Yes >=8.5" No Yes
Slate No >=8.5" Yes Yes
All other devices Doesn't matter All sizes Yes Yes

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 of 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 setting for new installations.
