About TouchPad Drivers:

Windows operating systems automatically apply a generic driver that allows users to benefit from basic touch functions; however, advanced features will not be available until the proper files are installed.

When enabled by required software, the touchpad component is recognized by computers and all developed features are made accessible.

Even though touchpoint technology is mostly associated with notebooks or laptops, other systems can also benefit from it with the help of an external wireless or wired TouchPad device.

If you wish to update to this version, know that it can enhance overall performance and stability, add different fixes for various touch problems, improve existing gestures, or even include support for new ones.

As for the installation procedure, first make sure that all system characteristics are supported and only then save and install the downloadable package. Even if other OSes might be compatible as well, we do not recommend applying any software on platforms other than the specified ones.

With this in mind, follow all aforementioned steps and apply the present release. Should you choose not to update right now, check back with our website again to stay up to speed with latest releases.
