fix lenovo touchpad gestures in windows 10

Install the latest driver from Lenovo support download. For me, it was Synaptics_V19.0.9.5_Elan_V11.4.63.4_fix.exe. With the fresh install, default configuration, following key bindings are working:

• 3 finger tap - cortana
• 3 finger swipe down - minimize all windows
• 3 finger swipe up - task view
• 3 finger swipe left/right - switch tasks(alt/tab)
• 2 finger swipe up/down - scroll up down

to enable two gingers tap as right click, follow instructions below and the screen capture below:

1.Press Win+R keys to open run, type regedit and hit enter to open Registry Editor.
2.Go to "HKEY_CURRENT_USER\Software\Synaptics\SynTP\TouchPadPS2". If you don't find "TouchPadPS2" and another entry named "TouchPadS...." exists under SynTP then click on "TouchPadSMB2c". If you don't find "SynTP" key then read note at end of the post.
3.On the right double click on "MultiFingerTapFlags" entry and update its value to 3 if it was 0, need to be changed, otherwise might just leave this.
4.On the right double click on "2FingerTapAction" entry and update its value to 2.

Noticed that under LocalMachine 3 finger gestures were added:
