You can use different keyboards with Windows to fit your needs. The most common is a physical, external keyboard that you plug into your PC. Windows 8 also include a touch keyboard for PCs with touch.
On touch PCs (ex: laptops or tablets), you will notice that if you turn off the “Touch Keyboard” toolbar, it may automatically be turned back on again after a restart.
This tutorial will show you how to enable or completely disable the Touch Keyboard toolbar on the taskbar for all users in Windows 8 and 8.1.
