As users continue to update their Surface, Surface 2, ARM, and x86-based tablets to Windows 8.1 Update, many are finding that the power button, the one that allows you to sleep, shut down, and restart the device, is missing. the top right corner of the home screen on tablets.
According to Microsoft, not all devices will have an on/off button, as the feature is connected to a setting called the “power platform feature” defined by PC manufacturers.
If the PC is set to “slate”, the power button after installing Windows 8.1 Update will not appear, because tablets are not designed to be turned off and users can easily press the button by mistake.
If the device is defined as a “mobile device”, for example, laptop or Ultrabook, the power button will appear on the Home screen.
Now, as with all new features in Windows or any other software, there will be customers who want to see a specific feature on all their devices. So, if your laptop has a power on/off button, but your tablet doesn’t, you can use the following registry settings to add the power on/off button to Surface or any other tablet (ARM or x86).
Note: This tweak can also help if you installed Windows 8.1 Update on your laptop and the feature just didn’t appear.
1. Go to the Home screen, perform a search regedit.exeand open Registry Editor.
2. Navigate the following route:
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion ImmersiveShell
3. Right click ImmersriveShell folder (or node), select New and in the menu choose Key.
4. Name the new key Rocket launcher.
5. Inside the Rocket launcher folder, right click, select New and choose DWORD value (32-bit). Then name the new value Launcher_ShowPowerButtonOnStartScreen.
6. The default value for Launcher_ShowPowerButtonOnStartScreen is 0. If left at the default value, the options for the power button after installing the Windows 8.1 update will not appear on the Start screen. If you double click, edit the value to 1and restart the PC, the Power button will appear on the Start screen.
Note: If that doesn’t work for you, just delete Launcher_ShowPowerButtonOnStartScreen and recreate it.
Attention: Although this method is not particularly difficult to do, editing the Windows Registry can sometimes be complicated and harmful to your computer. Before making any changes, backup the registry or create a restore point in Windows.
