Lower the touchpad sensitivity—or enable Palm Check/Palm Guard if your laptop provides it—because unintended touchpad contact while typing commonly moves the insertion point in both Word and email. ^1^
Change the touchpad settings
Windows 11
- Open Start → Settings → Bluetooth & devices → Touchpad.
- Expand Taps.
- Set Touchpad sensitivity to Medium or Low.
- If shown, enable Palm Check, Palm Guard, or palm rejection.
- If jumping continues, temporarily turn off:
- Tap with a single finger to single-click
- Tap twice and drag to multi-select
- Three- and four-finger gestures
- Type for several minutes in Word or an email to test the change.
Windows 10
- Open Start → Settings → Devices → Touchpad.
- Reduce Touchpad sensitivity.
- Disable tap gestures temporarily and test again.
Windows exposes touchpad sensitivity and tap controls in these locations, although the options available can vary by laptop. ^2^
Isolate the touchpad
Temporarily turn off Settings → Bluetooth & devices → Touchpad, then type using an external mouse.
- Jumping stops: the touchpad settings, driver, or hardware are responsible.
- Jumping continues: the touchpad is unlikely to be the source; disconnect other input devices and test again.
Also wipe the touchpad gently with a dry cloth, since moisture or debris can produce unintended input. A problem that disappears while the touchpad is disabled can indicate faulty touchpad hardware. ^3^
If changing sensitivity does not fix it
Update the touchpad driver through Windows Update, which is Microsoft’s recommended method:
- Open Settings → Windows Update → Advanced options → Optional updates.
- Open Driver updates, if present.
- Install any touchpad or input-device driver.
- Restart the laptop, even if Windows does not request it. ^4^
If no update is offered, reinstall the driver:
- Save your work and close all applications.
- Right-click Start → Device Manager.
- Expand Human Interface Devices and Mice and other pointing devices.
- Locate the touchpad—its name might include the laptop manufacturer, ELAN, Synaptics, or Precision Touchpad.
- Right-click it and select Uninstall device, then confirm.
- Restart Windows; Windows will attempt to reinstall the driver automatically. ^5^
If Windows does not provide a suitable driver, obtain the touchpad driver only from the laptop manufacturer’s official support site. If the insertion point still jumps while the touchpad is disabled, or the behavior returns with a manufacturer driver installed, contact the laptop manufacturer for hardware testing. Microsoft likewise recommends manufacturer support when updating or reinstalling the touchpad driver does not resolve the issue. ^6^
