Word prediction in Windows is a feature that suggests words you can type next, based on what you’ve typed so far. This can save you time and make it easier to type text on a computer.
It can in many ways be compared to the word suggestions you get on your phone when you write a message.

In the video below, Mike Tholfsen from Microsoft shows how to turn on Word Prediction.

Go to «Settings», search for «Text suggestions», then select «Show text suggestions as I type on the hardware keyboard», and voila you’re done!
