I know what I exactly need to do, system restore. Sadly I did not set my C drive any restore point. So I left with one more options which is reset my Windows to previous Build.
Simply type reset this pc in your search bar, now on the next screen select second option which allows you to reset your pc into previous build.
Now just plug in power chord, the process takes about 30 minutes (for my laptop). When it restart the touchpad still does not work, but actually you just need to press Fn + F7 keys to re-activate your Touchpad, and I did get my 2 finger scrolling function.
Here is another guide I collected during my research to fix this problems, hope it will help you out too without having to revert to previous build:
