--This applies mostly to tablet type devices, but it appears to work on other laptops that have windows 8 installed. Windows 8 has been causing a lot of trouble, especially with the touch functionality. Even though this says its for the surface, give it a go and lets see your results. Apparently it worked on a few different models of laptops. Its a fix for the Win 8 OS.
The main thing is to uninstall and reinstall the correct driver for your computer - If you havent done it THIS WAY, try it this way now and lets see if it works:
Step 1: Disable Windows from installing drivers automatically.
On the Start screen, type System.
Click on System to open System properties.
From the left pane, Click Advanced system settings.
Go to the Hardware tab.
Click on Devices installation settings.
Click on No.
Check No, never install driver software from Windows updates.
Step 2: Uninstall Existing Drivers
Press Windows Key + X.
Click on Device Manager.
Locate the touch drivers.
Disable and Uninstall the Drivers.
Restart the computer for these Settings to take effect.
Step 3: Download and Install correct drivers
Visit your Computer Manufacturer’s Driver download webpage.
Download and install the touch drivers.
Restart the computer.
What is the full model number for your machine? I will find you the touch driver on the website.
If this doesnt work, you may want to look into reinstalling the entire windows 8 operating system from a recovery disk. If you dont have one, we can help you get one.
