ASUS USB Ports and Touchpad Not Working after Windows 10 update

Hello,

I recently received an update to my ASUS Vivobook laptop which was running windows 10, quite flawlessly I might add. After the update, my touch pad stopped accepting multi-touch and my USB ports stopped recognizing any devices including my mouse. It would not even give a "device not recognized" notification. It just is not detecting the devices.

I first tried to fix my touch-pad by unistalling the SmartGesture driver and reinstalling. Nothing changed. The touchpad only accepts one finger operations so it does not allow for two finger scrolling etc. I read a post that said you don't need SmartGesture because Win10 comes with its own drivers to allow the touch-pad to do those multi-touch things but its still not working.

I tried to fix the USB ports by first changing the power management to not turn off the ports in power saving mode. Didn't work. Then I tried reinstalling the drivers using the Device Manager. Didn't work. Then I tried to uninstall all the USB drivers within Device Manager and restart my laptop and let it reinstall itself. Didn't work. The ports are not faulty because they were all working before the update and I know that my mouse is working and that all the cords and flash drives I plug in are working because I tested them on another PC.

I need help.

Thanks for the advice.

I tried the system restore but during the restore, it said "your pc has ran into a problem and needs to restart" and something about "inaccessible boot device". Then it tries to restart but it goes to a blue screen saying "your pc did not start correctly" and gives 2 choices: restart and advanced options.
I tried restart but it just comes back to this point.

What do I do now ?

Ok thanks I will try that now.
Questions:
do I lose all my personal files in this process?
What would happen if I tried to reset the PC from the Advanced Options that came up?

I would suggest updating the USB 3.0 drivers, probably Intel. I just fixed 3 Laptops at work that had bad USB 3 drivers and the USB ports would not work.

Also, I do not have a Windows 10 product key because my laptop came with Windows 8 pre-installed and I simply upgraded to Windows 10. Would that be a problem?
