Q: I applied Windows 8.1 Update 1, but I don't have a Power button on the Start screen. Where can I get one?

A: Windows 8.1 Update 1 introduced several usability enhancements, primarily focused around keyboard and mouse interaction. One of these changes was a Power button on the Start screen (next to the new Search button) to provide easy access to Power commands for the machine.

On some machines, specifically machines that support connected standby, the Power button isn't visible. This is because you typically don't want to shut down connected standby devices; instead, you should use the built-in power button on the physical device.

To control whether the Power button shows on the Start screen, follow these steps:

  1. Start the registry editor (regedit.exe).
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell.
  3. From the Edit menu, select New, Key. Name it Launcher, then select the new key.
  4. From the Edit menu, select New, DWORD value.
  5. Enter a name of Launcher_ShowPowerButtonOnStartScreen and press Enter.
  6. Double-click the new value and set it to 0 to not show the Power button or 1 to show the Power button.

You need to log off and log back on for the change to take effect.

You can also use the following registry file (change the value to 0 or 1 depending on what you need); save as powerstart.reg:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\Launcher]
"Launcher_ShowPowerButtonOnStartScreen"=dword:00000001
