Sort the entries by name, and look for the process called 'Synaptics Touchpad 64-bit Enhanceents. Right-click on it and select End process.
As the earier posted mentioned, the process will respawn immediately and will reload the registry entries, thus restoring the correct behavior. BTW I've done some more experimenting. Virtualbox seems to be implicated, but the swipe up/down gestures only disappear after my laptop goes to sleep and then automatically hibernates---not if I put it to sleep and wake it up before it hibernates, or if I put it into hibernate nmode directly. The jury is still out on Chrome. Thanks for the update. For me killing the SynTPEnh process in task manager doesn't work correctly and the taskkill command only works with command switch /F (force kill). I used the taskkill command in my Scheduled Task because I don't want to do this manually.
