The driver software in the Settings/ Devices/ Mouse and touchpad/. I have a Sony Vaio laptop, SVE14A1C5E, which I upgraded to Windows 10.
Please try the following methods to solve this issue: Method 1: Run the Hardware and devices troubleshooter. In some cases, the device or program might not work or may require an update, or you might need to uninstall some programs, and then reinstall them after installing Windows 8.1 Preview. Hi Abdulzxhamzx, Windows 8.1 Preview should work with the same devices and programs that work with Windows 8.
