Synaptics device drivers are customized to meet device manufacturers' specific driver requirements.
To ensure getting the appropriate driver for your device, download the Synaptics driver from your device manufacturer's support website. If you are upgrading to Windows 10 you can use your device's Windows update function to ensure you get the correct driver for your hardware.
Installing a generic driver may result in the loss of OEM-customized Synaptics pointing device functionality. Setting a restore point before installing is a quick way to rollback to the previous driver.
