To use touchpad gestures in Windows 10, you need to first set them in settings.

Search for Settings in the search tool. From there, navigate to Devices>Touchpad. Here, you can set gestures.

Scroll down to find the heading Three Finger Gestures. Click on the drop down bar to select your preferred option. If you want to control media play back, you can set this to the Change audio and volume option. Selecting this will allow you to increase or decrease volume while scrolling up or down on the touchpad with three fingers. Swiping left or right will allow you to navigate through playback. You can also set three finger taps to your preferred option. You can set it to pause/play media playback.

You can also set four finger gestures to your preferred option. This can include switch desktop and show desktop, change audio and volume or switch apps and show desktop.

You should now be able to use 3 and 4 finger gestures in Windows 10.
