I have an HP Sleekbook and was able to turn off the gestures (FINALLY!!) by following these steps.

1. Go to start screen
2. Select the settings block under the search bar on the right side.
3. In the search bar begin typing enable edge swipes or edge swipes.
4. Click on the 1st option that comes up (it looks like a gear) [This is under PC settings]
5. Where it says enable app gestures click OFF....
