Here are answers to some common questions about touch and pen settings.
Try using your finger to tap a tile on Start. If it’s a touch screen, the application will open. You can also check your current system settings with your mouse:
Swipe in from the right edge of the screen, tap Settings, then tap Change PC settings.(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, click Settings, then click Change PC settings.)
Tap or click PC and devices, and then tap or click PC info.
Under PC, check the Pen and Touch setting. It'll describe what sort of input your screen supports.
If you have a touchscreen, touch input is on by default and can’t be turned off. If you expect your laptop or monitor to respond to touch and it doesn’t, check the manufacturer’s website to make sure that it supports touch and that you have the correct drivers installed.
To adjust how accurately your screen senses when you use a pen or finger:
Swipe in from the right edge of the screen, then tap Search.(If you're using a mouse, point to the top-right corner of the screen, move the mouse pointer down, then click Search.)
Enter Calibrate in the search box, then tap or click Calibrate the screen for pen or touch input to open Tablet PC Settings.
Check that the monitor shown in the Display field matches the screen that you want to calibrate.
Tap or click Calibrate, then follow the on-screen instructions.
If you have calibrated your touch and pen settings, and the charms no longer appear when you swipe in from the right edge of your screen, it's possible that Windows isn't detecting the edge of your screen accurately because the screen boundary has been reset during the calibration. Try following these steps to calibrate your pen and touch settings again.
Tap or click Reset
You might be asked for an admin password or to confirm your choice.
If resetting your pen and touch settings doesn't work, then try calibrating again by tapping or clicking Calibrate, and then following the on-screen instructions. To help make sure Windows can detect the edge of your screen accurately, try touching slightly closer to the center of the screen when you touch the calibration points.
If you have two monitors and one is a touchscreen, the touch input signal can get mixed up. For example, touching one monitor will make the cursor move on the other monitor. To fix the problem:
Enter Calibrate in the search box, and then tap or click Calibrate the screen for pen or touch input to open Tablet PC Settings.
Tap or click Setup, then follow the on-screen instructions.
To change how fast or far an action is, or how long it takes:
Enter pen and touch in the search box, and then tap or click Pen and Touch.
Tap or click the action you want to configure, and then click Settings.
Follow the on-screen instructions.
