Not 100% sure this will fix your problem but this is how you uninstall the drivers that zadig made for you.
Go where it says "Type here to search" and type in device manager, open it and on top choose view and check show hidden devices, go to portable devices and right click on SWITCH and choose uninstall device.
Maybe if that doesn't solve your problem check your computer's system restore there should have been a restore point made at the time you installed the drivers, restore your computer to that point to revert back to how it was.
