Touchpad disables when using keys. Why, and how can I fix it?

Hi. You obviously know why I'm here, so I'll get right to the point.
[I'm using a Windows 10 Lenovo laptop]

When I'm playing games that require moving your and using keys at the same time, it doesn't work. As usual, the keys completely disable/override the touchpad apart from the left/right click.


If you can, please answer me.
