Keyboard Automatically Typing on Windows: How to Fix It

If your Windows keyboard keeps entering characters without you pressing keys, the cause may be a stuck key, an attached device, an accessibility setting, or a driver problem. Work through these checks in order, starting with the quickest ways to rule out physical causes; you will not need to change advanced settings unless simpler fixes fail.

What You’ll Need

• A way to disconnect and reconnect your keyboard, such as access to its USB cable or wireless receiver.
• If available, a second keyboard or another computer to help identify whether the problem is with the keyboard or Windows.
• Save your work before restarting Windows or uninstalling a device.

Step-by-Step

1. Check whether one key is stuck. Notice which character repeats. Look for a key that is physically held down, obstructed by debris, or slow to spring back. Turn off or disconnect the keyboard before gently clearing visible dust around the key. Do not pour liquid or spray cleaner directly into it. If the keyboard has been exposed to liquid, disconnect it and let it dry fully; do not keep testing it while wet.
2. Disconnect other typing devices. Unplug the keyboard, then remove any USB receiver, game controller, macro pad, or other device that can send keystrokes. For Bluetooth keyboards, switch the keyboard off. Wait a few seconds and see whether typing stops. If it does, reconnect devices one at a time to find which one is sending input. A laptop’s built-in keyboard may still be active even when an external keyboard is connected.
3. Restart Windows. Save open files, select Start > Power > Restart, and test the keyboard after signing back in. A restart can clear a temporary input or driver problem. If you cannot use the keyboard to select Restart, use the mouse or touchpad. Avoid holding the power button unless Windows is unresponsive, because that can discard unsaved work.
4. Check accessibility keyboard settings. Open Settings > Accessibility > Keyboard in Windows 11, or Settings > Ease of Access > Keyboard in Windows 10. Turn off Sticky Keys and Filter Keys temporarily, then test again. Filter Keys changes how Windows handles brief or repeated keystrokes; it is more likely to affect key response than to cause characters to appear on its own, but checking it rules out an unexpected setting. Turn features back on if you rely on them.
5. Test the keyboard outside the affected app. Open Notepad from the Start menu and wait without touching the keyboard. If characters appear there too, the issue is not limited to one app. If they appear only in one program, close and reopen that program, check its input or macro settings, and test another text field. Also make sure a text field does not have focus while you are diagnosing; an active field will show any incoming keystrokes.
6. Reconnect or re-pair the keyboard. For a wired keyboard, try another USB port and connect it directly to the PC instead of through a hub. For a wireless keyboard, check its power, turn it off and on, and reconnect its receiver. For Bluetooth, open Settings > Bluetooth & devices in Windows 11 or Settings > Devices > Bluetooth & other devices in Windows 10. Remove the keyboard, then pair it again using the keyboard maker’s normal pairing procedure. Menu wording can vary slightly by Windows build.
7. Update or reinstall the keyboard device. Right-click Start and open Device Manager. Expand Keyboards, right-click the relevant keyboard, and choose Update driver > Search automatically for drivers. If that does not help, choose Uninstall device, then restart the PC; Windows normally detects the keyboard again. If you use a wireless receiver, check Human Interface Devices as well, but do not uninstall unfamiliar devices. If the problem began after a recent driver update, use the device’s Properties > Driver tab and choose Roll Back Driver if that option is available.
8. Compare with another keyboard or computer. If possible, test your keyboard on another computer, or test a known-working keyboard on yours. If the original keyboard repeats keys on another computer, it likely needs cleaning, repair, or replacement. If multiple keyboards behave the same way on this PC, focus on Windows settings, recently installed input software, or the computer’s hardware. On a laptop, a repair shop or manufacturer support can check the built-in keyboard if the fault persists.

Common Mistakes

• Changing many settings at once: Make one change, test, and note the result. Otherwise, it is hard to tell what fixed or worsened the problem.
• Assuming every repeated character is a Windows fault: A physically stuck key, wireless interference, or a faulty keyboard can produce the same symptom.
• Uninstalling unrelated devices: In Device Manager, remove only the keyboard device you can identify. Do not delete system devices or drivers at random.
• Cleaning with liquid while connected: Disconnect a wired keyboard or switch off a wireless one first. Never pour liquid into the keyboard.
• Forgetting to test another app: A program-specific macro or input issue can look like a Windows-wide problem.

Tips

• Write down which key repeats, whether the issue starts immediately or after a delay, and whether it happens before signing in. These details help narrow down the cause.
• For a quick test, disconnect an external keyboard and use the mouse to open Notepad. If typing continues, another input device or software may be involved.
• If the issue began after installing keyboard customization, macro, or gaming software, quit that program and test again. Re-enable it later only if the problem stays fixed.
• Keep important work saved before troubleshooting. A keyboard that sends repeated commands may activate shortcuts or enter text in the wrong window.

Troubleshooting

It keeps typing while the keyboard is unplugged: Check for a second keyboard, wireless receiver, controller, or other input device. If none is connected, restart Windows and test in Notepad. If the problem is limited to one app, close that app and inspect its input settings.

It starts again after a restart: Disconnect the keyboard and any receiver, then restart. If the symptom stops, reconnect devices individually. If it continues with all external input devices removed, consider recently installed input software or a laptop’s built-in keyboard.

It happens only with a wireless keyboard: Replace or recharge its batteries, move the receiver to a direct USB port, and bring the keyboard closer to the PC. Remove and re-pair a Bluetooth keyboard if reconnecting does not help.

Windows does not reinstall the keyboard: Restart with the keyboard connected and check Device Manager again. Use the mouse to navigate if needed. If Windows still does not recognize it, try another USB port or a different keyboard. Avoid downloading drivers from unofficial sites.

The keyboard repeats keys before Windows loads or on another computer: This points toward a physical keyboard fault rather than a Windows setting. Stop using a liquid-damaged keyboard and arrange repair or replacement. For a built-in laptop keyboard, contact the device manufacturer or a qualified repair service.

Frequently Asked Questions

Why is my keyboard typing by itself?
A stuck or damaged key is common, but a connected input device, keyboard software, accessibility setting, or driver issue can also be responsible.

Can Filter Keys cause automatic typing?
Filter Keys changes how Windows responds to brief and repeated key presses. It is not the usual cause of typing without a press, but turning it off temporarily is a useful test.

How can I tell if the keyboard is broken?
Test it on another computer if possible. If the same key repeats there, the keyboard itself is likely faulty. If another keyboard also misbehaves on your PC, investigate Windows or the PC instead.

Should I uninstall the keyboard driver?
Only after simpler checks. Uninstall the identifiable keyboard device in Device Manager and restart; Windows normally detects it again. Do not remove unfamiliar devices.

What if my laptop types by itself?
Disconnect external keyboards and receivers, then test again. If the built-in keyboard continues to send input, restart and check settings; persistent symptoms may require hardware service.

Will restarting delete my files?
A normal restart does not remove saved files, but it can discard unsaved work. Save open documents before restarting.
