Solved Disabling the touch screen

Right so I want to disable my touch screen because my friends at collage are very good about piddling me off (as banter). And I would like to know how I can disable it with the push of a button.
Any help?

Hi, try these steps.

a. Winkey + Q.
b. Type Control Panel.
c. Go to Hardware and Sound.
d. Pen and touch.
e. Click the touch tab.
f. Disable use your finger as an input.

I have looked in there and there is an option to disable t but it's grayed out

1. Right-click and select "All Apps" at the lower right corner, then select Control Panel
2. Select Hardware and Sound
3. Select Device Manager
4. Select Human Interface Devices
5. From the list, look for the driver for the touch screen. This can be tricky since on laptop they are all listed as "USB Input Device". You can start disabling and re-enabling one at a time until the touch screen stops responding. You can also identify the touch screen by checking the Properties | Details and get the "Hardware Ids" then do a search online to see what the device is.
6. Once you know which is the touch screen, disable the driver and the touch screen should no longer work
Enable this device to make the touch screen work again.

Thanks it worked by disabling the only USB device

Glad the issue is resolved. You can mark this is as solved.
