My mouse moves slower and I've lost the scrolling and zooming functions. I tried updating the driver and rolling back the driver, but neither worked. How can I restore the functions back to my mouse?
Just because 2 things happen around the same time does not mean that one event caused the other. The failure of the mouse probably had nothing to do with the Windows update.
You have not given enough information!
Laptop or desktop? On a laptop there are keyboard combinations that can disable the mouse pad.
Wireless? Do you need new batteries?
If it gives the same issues on another computer (a relatives or friends)
then replace it.
Put the mouse into another port. Maybe you need a new one.
It's probably hungry
