Hello Vazi, welcome to the community,
unfortunately the information that I have is that the IdeaPad 100 15IBY doesn't support multi-touch gestures.

There is for sure something wrong with the win10 driver. If you try to open the mouse settings from the (old) control panel it takes about 2min before the dialog box appears. By then the usual touchpad tab is missing.
Without this functionality a touchpad is practically useless. Lenovo please fix this!

The touchpad, if it works, accepts multitouch, there are even videos in the drivers folder how to use them.
BUT: The driver doesn't work properly:
Scrolling (either 2-finger or side-of-pad) with Sentelic Touchpad doesn't work. Somehow the driver application for gesture modification etc. doesn't start.
OS: Windows 10, 64 bit

for ideapad 100 users who has sentelic touchpad, to make all gestures incl 2 finger scroll work, do following
download synaptics driver - http://www.synaptics.com/en/drivers.php
disable driver signature enforcement (this is slightly unsafe, read about risks and decide for yourself)
then unzip and install driver manually through device manager:
open ps/2 compatible mouse device
Go to Driver tab and select Update Driver
Select Browse my computer for driver software
Select Let me pick from a list of device drivers on my computer
Select Have Disk...
Select the extracted driver folder
agree to install driver without digital signature.
after reboot synaptics icon will appear in the tray, and all gestures will start to work.
to lenovo rep: win 8.1 and win 10 driver for ideapad's 100-15iby sentelic touchpad could not be installed correctly, after install and reboot sentelic tray app closes itself. this is why scroll doesnt work.
driver downloaded from windows 10 auto update also has the same problem, because it is the same driver which is available from lenovo ideapad's 100-15iby support page.
so do your work and tell those dumb driver programmers that they need to fix this sh1tty driver or to ask synaptics to sign generic one for them.
this is only lenovo's fault for supplying driver that doesnt work.
sentelic touchpad itself are near-clone of synaptics touchpad, and has all multitouch capabilities of it(3 finger). with correct driver it works out of the box, you can witness this in linux.
Mod's Edit: Marked this posting as the Solution since is has verfied responses that it worked.

I tried what you explained in this post and must say - Thank you.
I'm using Lenovo Ideapad 100-15IBY
Now after all the time spent on trying to fix the gestures, I can scroll using the touchpad. And I need it, because most of the time I'm using it for typing (programming) and I really like the idea not to use mouse when I don't need it. I knew it wasn't the laptop fault, because on Ubuntu I got the dualtouch from first boot...
