It’s been possible to insert emojis into the screen shortcut for a long time. For those who use these colorful icons regularly, you can attach the screen shortcut to the tray to make them easier to access.
Right-click on an empty space on the taskbar and select Show Button for Touch Keyboard. Click on the icon in the taskbar to bring up the on-screen keyboard, and a click on the smiley icon will show you all the emojis.
Windows 10 also has a second on-screen keyboard shortcut, found in the Start menu under Easy Access, but it doesn’t have emojis.
