win 10, thinkpad t460 synaptics 3 finger gestures dont work

I am using Win 10 Edu with T460 Synaptics Touchpad and I have the same problem with losing 3 finger gesture after standby. Therefore I checked the registry as beforementioned in another topic. But I dont know what to change there into what. Can so help me? I am not so familiar with this IT stuff.

All drivers were updated recently. So that cant be the problem.
