Keyboard Gone Mad and Typing on Its Own? 6 Ways to Fix It on Windows | #microsoft | #hacking | #cybersecurity


It is not uncommon for the keyboard to malfunction from time to time. Some of the most common issues that users can face with the keyboard include specific keys that don’t work, some shortcuts that don’t register, and sometimes the keyboard ceasing to work altogether.

Another common keyboard issue users face is when keys begin to register on their own as if the keyboard has gone crazy. Such an issue stems from both hardware and operating system sides. If you are experiencing a similar issue, we’ll cover some fixes you can try to get it back on track.


1. Rule Out Hardware Issues

Hardware issues need to be ruled out first. Before moving on to more major fixes, perform the following checks:

  1. Disconnect your keyboard and reconnect it again.
  2. Make sure no keys are stuck while being pressed.
  3. Inspect the keyboard cable for potential damage.
  4. Make sure the connecting ports are intact and clean them if possible.

When you have determined that hardware isn’t the issue, check if the keys registering aren’t being pressed. To check that, go to the keyboard tester website and run a test to see what keys are being pressed.

If some keys are registering despite not being pressed, then there is a problem with those keys’ internal mechanism that needs an examination. In that case, try connecting the keyboard to another computer to confirm that the issue lies with the keyboard itself.

Replacing the keyboard will resolve the issue. Therefore, grab another keyboard (if you have one) and connect it to the computer. When issues go away further confirms that the problem lies with hardware.

However, if the issue persists with the new keyboard, the issue is operating system-related and needs to be looked into further.

2. Update Your Keyboard Driver

If your keyboard is acting abnormally due to OS-relevant issues, the first possible cause could be outdated keyboard drivers. Therefore, update the drivers to eliminate this possibility.

Follow these steps to update your keyboard drivers:

  1. Left-click on This PC and go to Manage.
  2. Go to the Device Manager in the left sidebar.
  3. Expand the Keyboards category in the right-hand pane.
  4. Right-click on the keyboard driver.
  5. Click on Update driver.

When the drivers are updated, check if the keyboard behaves the same way. If yes, diagnose the issue with the Windows built-in troubleshooter.

3. Run Keyboard Troubleshooter

Using troubleshooters can assist in automatically resolving the issue occurring on a Windows device. A dedicated keyboard troubleshooter is available to help users with keyboard issues.

To run a keyboard troubleshooter, follow these steps:

  1. Go to Windows Settings app.
  2. Navigate to Update and Security.
  3. Go to Troubleshoot in the left-sidebar.
  4. Click on Additional troubleshooters in the right-hand pane.
  5. Locate the Keyboard troubleshooter from the list.
  6. Click on it and hit Run the troubleshooter.

Follow the on-screen instructions and give the troubleshooter some time to diagnose the keyboard settings problem. The troubleshooter either diagnoses and resolves the issue on its own or reports that it failed to do so.

When that happens, it’s time to tweak your keyboard settings.

4. Tweak Keyboard Settings

You might be able to fix the issue by tweaking your keyboard settings. Therefore, temporarily disable any customizations you’ve made. Among them are disabling the sticky keys, disabling mouse control from the keyboard, and turning off the filter keys.

Follow these steps to manage these settings:

  1. Go to Windows Control Panel.
  2. Go to Ease of Access > Ease of Access Center.
  3. Click Make the keyboard easier to use in the right-hand pane.

  4. Uncheck the boxes for Turn on Mouse Keys, Turn on Sticky Keys, and Turn on Filter Keys.

See if reverting these customizations has made a difference. If not, continue implementing the following fixes.

5. Run a Malware and SFC Scan

Due to software interference, malware infiltration can also cause your hardware devices to malfunction. Hence, it’s imperative to ensure that this doesn’t happen here.

You can do this by running malware and SFC scan. As the malware scan fights against existing viruses and removes them from the vicinity of your computer, SFC will repair corrupt or damaged Windows files to ensure that no malicious files remain on your computer.

You can use third-party tools to remove malware, but the best and free method is to use Microsoft Defender’s offline scan. Are you running it for the first time? Read our article on how to remove malware using Microsoft Defender’s offline scan.

To run an SFC scan, follow these steps:

  1. In the Windows search box, type “cmd.”
  2. Right-click on the Command Prompt app and select Run as administrator.
  3. Enter the “sfc /scannow” command and hit Enter.

Wait for the command prompt to complete the verification process. After it has been completed, you will be informed about any possible issues that have been either automatically removed or you will have to remove manually.

If malware and SFC scans fail to resolve the issue, update your operating system as a last resort.

6. Update Your Operating System

Updating your operating system ensures there is no compatibility issue, making your keyboard go crazy. Check out our article to manage Windows updates the right way.

If the issue started after updating your OS, reverting the update holds a good chance of resolving the issue. For those of you who have never reverted an update, we have an article on how to revert Windows 10 to an earlier version.

If updating or downgrading the operating system does not solve the problem, there are two possible ways out of the problem: disable specific keyboard keys or use the on-screen keyboard.

Possible Alternatives to Keep Using Keyboard

You can try the following two solutions to continue using the keyboard despite the issue not being resolved:

Disable Certain Keys

The simple way to fix this issue is to disable the keys being pressed automatically. Even though there are different ways to disable keyboard keys, the best way is to use third-party tools.

To disable specific keyboard keys, KeyTweak and AutoHotKey are two easy-to-use tools. Check out our article explaining how to use these tools to disable specific keys on your keyboard.

Use On-screen Keyboard

You can disable specific keys, but you may see almost all keys registering automatically. In that case, you may need to disable the keyboard itself temporarily rather than selective keys. While you do that, you can still use the keyboard on the screen to continue working.

If you are unsure how to enable the on-screen keyboard in Windows, check out our article on how to enable and disable the on-screen keyboard in Windows.

Keyboard Back on Track or Not?

Hopefully, the fixes provided in this list will restore your keyboard’s full functionality. If none of the above solutions work, you might consider replacing the keyboard. When that does not work either, you may consider reinstalling the OS or doing a full reset.

To prevent this, open the keyboard keys that are being pressed automatically and clean underneath them. This may resolve the problem.
