Question: I have an Acer Aspire 5532, and it used to have a scroll option on it, on the side of the touchpad. I used a regular mouse plugged into the USB drive for a while, with the touchpad disabled, but it broke and I'm back to using the regular touchpad. however, somehow the scroll option got disabled and after quite a bit of trying I still can't figure out how to re-enable it. does anyone know how?

Answer: 
I fixed the problem by clicking Windows » Start, typing "touchpad" into search and clicking on "update drivers".

Update Synaptics, then restart and it'll all be good.
It's actually quite simple. Follow the below steps:
