If your screen cracks, or some other issues that disturb the touch function of the screen, you may want to disable it to keep using V.
Here is how you can do it:
go to Control Panel -> Device Manager (or just search Device Manager in Cortana)
in Device Manager, under “Human Interface Devices” find “HID-compliant touch screen”
right click it, choose Disable device, and confirm it in the prompt window
If needed, you can enable the touch screen later with the similar steps above
