Windows 10, 8, and 7 are designed to work well with touchscreens, but things can go wrong. When you tap the screen and it behaves as if you are tapping somewhere else, that usually indicates a calibration problem. Touchscreen calibration usually fixes those types of problems.

The Touchscreen Calibration Tool works by drawing a pattern on the screen and then overlaying it with a series of crosshairs. By tapping each crosshair in succession, you tell Windows exactly how to configure the touchscreen.
When calibrating a touchscreen, it is essential to tap the actual location of each crosshair. If you tap anywhere else, you will end up with an incorrectly configured touchscreen that may be unusable. In that case, connect a keyboard and mouse to reactivate the configuration tool.
Press the Windows logo key on your keyboard. This will open the Start menu and you can search for the screen calibration tool.
