Some users have reported after installing Windows 11 on devices with touch screens the virtual keyboard icon is missing from the taskbar. This can be very frustrating if you have a touch only tablet and you must plug in an external USB keyboard to be able to work. Don't worry, the virtual keyboard functionality is still in Windows, it is just hiding by default upon a new install. Follow these steps to enable the virtual keyboard icon on your taskbar.
First, head over the the Settings app by tapping or clicking on the Start Menu icon and then select Settings.
Next, select the Personalization section in the settings app.
Scroll down and select Taskbar.
Finally, under System tray icons, change the setting next to Touch keyboard to Always to ensure the touch keyboard icon is displayed.
