Click the Windows Start button and click the gear icon (Settings).
Click “Time & Language”.
In the left panel, click “Language”.
Click the “+” button next to “Add a language”.
Type “Korean” in the search box, and press Enter. The option for the Korean language will appear below the search box. Select 한국어 (Korean) and click “Next”.
There are 3 features that you can uncheck. Uncheck these options as below in the picture (Install Language Pack, Text-to-speech, Handwriting). Make sure to have the top 4 features unchecked. Click “Install”.
Now the Korean keyboard is implemented. You will notice a small icon (“ENG”) appearing in your taskbar in the bottom right corner of your screen. That icon is a button you will use to switch between the English-Only mode and the Korean-Enabled mode of your keyboard.
