Hello Avisek,
We realize the inconvenience you have experienced.
What is the status of touch pad driver in Device Manager? Press Windows logo key + X, select
Device Manager.
Spot and expand the “Mice and other pointing devices ”.
From the description, I suspect that the problem might be with the unavailable or incompatible touchpad drivers. Suggest you to check and install the latest Windows 10 touchpad drivers for your device from device Manufacturer website. You can search them
using your device model number. Go here
to download the drivers for your device.
Also check and confirm that your device is up to date with Windows Updates.
Go to Start Button/>Settings/>Update & Security/> Windows Update and click
Check the updates. If you find any driver updates for your device, then try to install them and see if they make any difference.
Let us know how it went.
